rk3399 是一款基于arm64的机器，我们这边一款产品是基于rk3399 Android 7.1版本的开发，我们的 vtest.apk包含多个so，在正常userdebug模式下不会出现兼容性问题，如果切换到user版本就会出现概率性崩溃的问题。并且崩溃不是vtest.apk而且其他system apk 比如StressTest、 keychain、exchange等apk 概率性崩溃。
首先明确一些系统，StressTest、 keychain、exchange都是系统 app 并且签名都是platform
vtest.apk (com.deepblue.vehicle)也是系统签app ，预制到系统中的。并且包含多个32位的so
Stresstest崩溃主要信息如下：

上面的日志有几句非常有用
01-18 08:50:15.640 581 581 I PackageManager: Adjusting ABI for com.android.rk to armeabi-v7a (requirer=com.deepblue.vehicle, scannedPackage=null)
01-18 08:50:15.640 581 581 I PackageManager: Adjusting ABI for com.android.location.fused to armeabi-v7a (requirer=com.deepblue.vehicle, scannedPackage=null)
Adjusting ABI for com.cghs.stresstest to armeabi-v7a (requirer=com.deepblue.vehicle, scannedPackage=null)
从这段可以看出stresstest 的ABI被调整位 armeabi-v7a 也就是32位，arm64-v8a为64位
ABI相关解释
ABI是Application Binary Interface的缩写。
ABI常表示两个程序模块之间的接口，且其中一个模块常为机器码级别的library或操作系统。
ABI定义了函数库的调用、应用的二进制文件（尤其是.so）如何运行在相应的系统平台上等细节。
Android目前支持以下七种ABI：armeabi、armeabi-v7a、arm64-v8a、x86、x86_64、mips、mips64。
对于rk3399 的64的系统。默认情况下apk 都是已运行在64运行，如何查看apk 运行情况，可以通过下面命令查看
rk3399_firefly_mipi_box:/ $ ps | grep zygote
root 200 1 2151024 123500 0 0000000000 S zygote64

system 1246 201 1572932 70468 0 0000000000 S com.cghs.stresstest
我们发现我们Stresstest运行在32的虚拟机上，很明显这里出现 了错误。由于我们 Stresstest 是system app ，所以情况有些特殊
对于rk3399中apk 有下面运行规则，
引用其他人总结
1、如果apk中的native库中含有arm64-v8a，则以64位的模式执行，fork zygote64
2、如果没有，则看有没有armeabi-v7a,armeabi这两个，如果有，则以32位模式执行，fork zygote
3、如果以上两个都没有，就查找共享shareuid 运行的情况。如果共享uid 运行32位就运行在32位，共享uid 运行64位就运行在64位，与共享uid运行在同一个虚拟机中。
4、如果apk中这三个库都没有，则默认以64位模式执行。
对于系统app
如果apk包中lib文件夹下有.so库，就根据这个.so库的架构模式，确定app的primaryCpuAbi的值
对于system app, 如果没法通过第一步确定primaryCpuAbi的值，PKMS会根据/system/app/${APP_NAME}/lib和/system/app/${APP_NAME}/lib64这两个文件夹是否存在，来确定它的primaryCpuAbi的值
对于还没有确定的app, 在最后还会将自己的primaryCpuAbi值与和他使用相同UID的package的值设成一样
对于到这里还没有确认primaryCpuAbi的app，就会在启动进程时使用ro.product.cpu.abilist这个property的值的第一项作为它关联的ABI
上面我们讲过的ABI对我们apk 最终的进程运行的架构有最终影响，这个影响是通过代码中的primaryCpuAbi值的确定，
影响primaryCpuAbi值相关代码在pacagemangeservice.java中
scanPackageDirtyLI() {
... ...
if ((scanFlags & SCAN_NEW_INSTALL) == 0) {
// 这个方法里会通过apk包里包含的so库的架构来决定app的primaryCpuAbi的值，主要功能把lib库的路径创建好了，也把lib库copy到这个目录下，然后后面会调用Installd的方法，在data/data/apk相关目录 下的lib 创建软链接到真正放lib的地方，如果32位库就会建立lib/arm，64位lib/arm64
derivePackageAbi(pkg, scanFile, cpuAbiOverride, true /* extract libs */);
// Some system apps still use directory structure for native libraries
// in which case we might end up not detecting abi solely based on apk
// structure. Try to detect abi based on directory structure.
if (isSystemApp(pkg) && !pkg.isUpdatedSystemApp() &&
pkg.applicationInfo.primaryCpuAbi == null) {
// 如果是system app，并且这个app没有通过上面的函数找到primaryCpuAbi的值
setBundledAppAbisAndRoots(pkg, pkgSetting);
// setNativeLibraryPaths方法会根据CpuAbi的值确定apk使用的so库的安装路径
setNativeLibraryPaths(pkg);
}
} else {
if ((scanFlags & SCAN_MOVE) != 0) {
// We haven't run dex-opt for this move (since we've moved the compiled output too)
// but we already have this packages package info in the PackageSetting. We just
// use that and derive the native library path based on the new codepath.
pkg.applicationInfo.primaryCpuAbi = pkgSetting.primaryCpuAbiString;
pkg.applicationInfo.secondaryCpuAbi = pkgSetting.secondaryCpuAbiString;
}
// Set native library paths again. For moves, the path will be updated based on the
// ABIs we've determined above. For non-moves, the path will be updated based on the
// ABIs we determined during compilation, but the path will depend on the final
// package path (after the rename away from the stage path).
setNativeLibraryPaths(pkg);
}
// 当前解析的apk是framework-res.apk, 对这个特殊的apk, 让它的ABI值的系统相同, 在我这里，它就是arm64-v8a
// This is a special case for the "system" package, where the ABI is
// dictated by the zygote configuration (and init.rc). We should keep track
// of this ABI so that we can deal with "normal" applications that run under
// the same UID correctly.
if (mPlatformPackage == pkg) {
pkg.applicationInfo.primaryCpuAbi = VMRuntime.getRuntime().is64Bit() ?
Build.SUPPORTED_64_BIT_ABIS[0] : Build.SUPPORTED_32_BIT_ABIS[0];
}
... ...
if ((scanFlags & SCAN_BOOTING) == 0 && pkgSetting.sharedUser != null) {
// We don't do this here during boot because we can do it all
// at once after scanning all existing packages.
//
// We also do this *before* we perform dexopt on this package, so that
// we can avoid redundant dexopts, and also to make sure we've got the
// code and package path correct.
adjustCpuAbisForSharedUserLPw(pkgSetting.sharedUser.packages,
pkg, true /* boot complete */);
}
}
接着先来看下derivePackageAbi()方法是如何确定primaryCpuAbi的值的：
public void derivePackageAbi(PackageParser.Package pkg, File scanFile,
String cpuAbiOverride, boolean extractLibs) {
// 这里会先设置一个默认的so库安装路径
setNativeLibraryPaths(pkg);
if (isMultiArch(pkg.applicationInfo)) {
// 这里处理的是支持两种abi的apk, 这种apk的AndroidManifest.xml里会设置android:multiarch为true
... ...
} else {
String[] abiList = (cpuAbiOverride != null) ?
new String[]{cpuAbiOverride} : Build.SUPPORTED_ABIS;
final int copyRet;
// 这是一个JNI函数，作用就是根据apk包里的lib/目录下的.so的ABI确定返回值
copyRet = NativeLibraryHelper.copyNativeBinariesForSupportedAbi(handle,
nativeLibraryRoot, abiList, useIsaSpecificSubdirs);
// 根据copyRet的值，确定当前app的primaryCpuAbi值
if (copyRet >= 0) {
pkg.applicationInfo.primaryCpuAbi = abiList[copyRet];
} else if (copyRet == PackageManager.NO_NATIVE_LIBRARIES && cpuAbiOverride != null) {
pkg.applicationInfo.primaryCpuAbi = cpuAbiOverride;
} else if (needsRenderScriptOverride) {
pkg.applicationInfo.primaryCpuAbi = abiList[0];
}
}
// 到这里有一些app已经确定了primaryCpuAbi的值，所以再调一次这个函数，更新它使用的.so库的安装位置
setNativeLibraryPaths(pkg);
}
通过这段代码会可以看出：
一些apk包里lib目录下有.so文件的，可以通过.so文件的ABI来确定app的primaryCpuAbi的值对于那些lib下没有.so文件的apk, 比如不使用so库的或者是系统app，运行完这个方法之后，primaryCpuAbi的值仍然是空 。
接下来看下系统app是如何通过setBundledAppAbisAndRoots()方法来确定primaryCpuAbi的值的：
private static void setBundledAppAbi(PackageParser.Package pkg, String apkRoot, String apkName) {
final File codeFile = new File(pkg.codePath);
final boolean has64BitLibs;
final boolean has32BitLibs;
if (isApkFile(codeFile)) {
// 只有framework-res.apk这个包会进这个if分支，has64BitLibs和has32BitLibs的值都是false
// 在前面scanPackageDirtyLI里有说过，这个app的primaryCpuAbi的值是arm64-v8a
has64BitLibs = (new File(apkRoot, new File(LIB64_DIR_NAME, apkName).getPath())).exists();
has32BitLibs = (new File(apkRoot, new File(LIB_DIR_NAME, apkName).getPath())).exists();
} else {
// 对于其它的app, codeFile是apk所在的路径
final File rootDir = new File(codeFile, LIB_DIR_NAME);
final String isa = VMRuntime.getInstructionSet(Build.SUPPORTED_64_BIT_ABIS[0]);
// 通过判断/system/app/${APP_NAME}/lib64这个文件夹是否存在决定has64BitLibs的值
has64BitLibs = (new File(rootDir, isa)).exists();
final String isa = VMRuntime.getInstructionSet(Build.SUPPORTED_32_BIT_ABIS[0]);
// 通过判断/system/app/${APP_NAME}/lib这个文件夹是否存在决定has32BitLibs的值
has32BitLibs = (new File(rootDir, isa)).exists();
}
// 下面这一段会根据has64BitLibs和has32BitLibs的值来确定app的primaryCpuAbi的值
if (has64BitLibs && !has32BitLibs) {
pkg.applicationInfo.primaryCpuAbi = Build.SUPPORTED_64_BIT_ABIS[0];
pkg.applicationInfo.secondaryCpuAbi = null;
} else if (has32BitLibs && !has64BitLibs) {
pkg.applicationInfo.primaryCpuAbi = Build.SUPPORTED_32_BIT_ABIS[0];
pkg.applicationInfo.secondaryCpuAbi = null;
} else if (has32BitLibs && has64BitLibs) {
if (VMRuntime.is64BitInstructionSet(getPreferredInstructionSet())) {
pkg.applicationInfo.primaryCpuAbi = Build.SUPPORTED_64_BIT_ABIS[0];
pkg.applicationInfo.secondaryCpuAbi = Build.SUPPORTED_32_BIT_ABIS[0];
} else {
pkg.applicationInfo.primaryCpuAbi = Build.SUPPORTED_32_BIT_ABIS[0];
pkg.applicationInfo.secondaryCpuAbi = Build.SUPPORTED_64_BIT_ABIS[0];
}
} else {
pkg.applicationInfo.primaryCpuAbi = null;
pkg.applicationInfo.secondaryCpuAbi = null;
}
}
根据上面的代码，可以知道：
对系统app而言，根据/system/app/{appNAME}/lib和/system/app/{appNAME}/lib64这两个文件夹是否存在，来确定它的primaryCpuAbi的值当然，如果系统app不存在上述两个文件夹，那它的primaryCpuAbi的值仍然为空
所以在经过上述操作之后，会存在以下四种情况：
无论是系统app还是第三方app, 如果apk包里lib目录存在.so文件，会根据.so文件来确定primaryCpuAbi的值如果是系统app, apk包里又不存在.so文件，就会进一步根据/system/app/{appNAME}/lib/lib和/system/app/{appNAME}/lib/lib64这两个文件夹是否存在，来确定它的primaryCpuAbi的值对于framework-res.apk为个特殊的apk文件，它的primaryCpuAbi的值由虚拟机是什么架构来决定，在我这里，它是arm64-v8a对于其余的apk, 它们的primaryCpuAbi的值仍然为空
我们重点分析adjustCpuAbisForSharedUserLPw这个函数
private void adjustCpuAbisForSharedUserLPw(Set<PackageSetting> packagesForUser,
PackageParser.Package scannedPackage, boolean bootComplete) {
String requiredInstructionSet = null;
if (scannedPackage != null && scannedPackage.applicationInfo.primaryCpuAbi != null) {
requiredInstructionSet = VMRuntime.getInstructionSet(
//这里根本不会被执行，？ 因为 scannedPackage = null
scannedPackage.applicationInfo.primaryCpuAbi);
}
PackageSetting requirer = null;
//循环取出共享一个uid 的 apk ，比如取出共享 system uid 的apk 组合
for (PackageSetting ps : packagesForUser) {
// If packagesForUser contains scannedPackage, we skip it. This will happen
// when scannedPackage is an update of an existing package. Without this check,
// we will never be able to change the ABI of any package belonging to a shared
// user, even if it's compatible with other packages.
// 会执行执行到这，因为scannedPackage == null
if (scannedPackage == null || !scannedPackage.packageName.equals(ps.name)) {
if (ps.primaryCpuAbiString == null) {
//查看取出的apk 的 ABI值是否为空，空就继续执行。直到取出一个不为空的。对于
//system uid 组合的apk ，大部分apk 并不存在so 库，所以大部分的primaryCpuAbiString = null，
//但是我们system uid 中的Vtes.apk 是有 32 so的，所以其 primaryCpuAbiString = armeabi-v7a（32位）
continue;
}
final String instructionSet = VMRuntime.getInstructionSet(ps.primaryCpuAbiString);
if (requiredInstructionSet != null && !instructionSet.equals(requiredInstructionSet)) {
// We have a mismatch between instruction sets (say arm vs arm64) warn about
// this but there's not much we can do.
String errorMessage = "Instruction set mismatch, "
+ ((requirer == null) ? "[caller]" : requirer)
+ " requires " + requiredInstructionSet + " whereas " + ps
+ " requires " + instructionSet;
Slog.w(TAG, errorMessage);
}
if (requiredInstructionSet == null) {
requiredInstructionSet = instructionSet; //instructionSet ===arm64
requirer = ps;
//requirer=com.deepblue.vehicle
}
}
}
if (requiredInstructionSet != null) {
String adjustedAbi;
if (requirer != null) {
// requirer != null implies that either scannedPackage was null or that scannedPackage
// did not require an ABI, in which case we have to adjust scannedPackage to match
// the ABI of the set (which is the same as requirer's ABI)
adjustedAbi = requirer.primaryCpuAbiString;
//把system uidi 的 adjustedAbi = armeabi-v7a
if (scannedPackage != null) {
scannedPackage.applicationInfo.primaryCpuAbi = adjustedAbi;
}
} else {
// requirer == null implies that we're updating all ABIs in the set to
// match scannedPackage.
adjustedAbi = scannedPackage.applicationInfo.primaryCpuAbi;
}
//这里 把 系统中primaryCpuAbiString = null 的值都赋值位 armeabi-v7a
for (PackageSetting ps : packagesForUser) {
if (scannedPackage == null || !scannedPackage.packageName.equals(ps.name)) {
if (ps.primaryCpuAbiString != null) {
//有值 的就跳过
continue;
}
ps.primaryCpuAbiString = adjustedAbi;
if (ps.pkg != null && ps.pkg.applicationInfo != null &&
!TextUtils.equals(adjustedAbi, ps.pkg.applicationInfo.primaryCpuAbi)) {
ps.pkg.applicationInfo.primaryCpuAbi = adjustedAbi;
Slog.i(TAG, "Adjusting ABI for " + ps.name + " to " + adjustedAbi
+ " (requirer="
+ (requirer == null ? "null" : requirer.pkg.packageName)
+ ", scannedPackage="
+ (scannedPackage != null ? scannedPackage.packageName : "null")
+ ")");
try {
mInstaller.rmdex(ps.codePathString,
getDexCodeInstructionSet(getPreferredInstructionSet()));
} catch (InstallerException ignored) {
}
}
}
}
}
}
根据上个代码的分析。我们stresstest、keychain 都是没有so的apk ，所以初始阶段primaryCpuAbiString = null，由于和Vtest.apk共享一个system uid ，所以它们都被置为32 位的 armeabi-v7a，因为他们都是system app 。源码编译出来的。默认只支持64的系统。
所以开机完成之后会报错。
为什么会概率性报错呢？
由于我们系统中共享system uid 除了 Vtest.apk有so之外还有一个apk 有so库，但是他们的so是64位的。开机完成之后如果这个apk 先于Vtest完成初始化。我们stresstest、keychain 都会与这个apk共享 64位的ABI，所以不会崩溃。
问题分析清楚了，怎么修改呢？
开始遇到这个问题我也与瑞芯微的FAE沟通，他们让我按照这个博客修改，对于这个问题有点鄙视他们解决方式
https://blog.csdn.net/qq_37610155/article/details/78607276
实际这个博客并没有解决我的问题，启动还是会有概率性崩溃，而且会有其他衍生问题
LOCAL_DEX_PREOPT := nostripping
DEX_PREOPT_DEFAULT := nostripping
这个属性会导致系统不优化整个系统 ，而且导致system.img很大。启动特别慢，
我解决思想是这样的。
1、对于其他共享uid的不做处理
2、对于共享systemuid的专门做处理，我们Vtest 我们跳过。直到遇到64的so的apk
相关的修改代码由于特殊原因就不列出来了，如果有需要的可以联系我
