tinker安装

1.从https://github.com/Tencent/tinker下载代码，然后用android studio打开tinker-sample-android

2.在module的build.gradle修改gitSha

def gitSha() {
   return 32323
}

如果不修改会报错，这个方法，也就是获取git最近一次commit的版本号，所以要是你的当前Project没有配置git，或者当前的Project还没有commit过，

或者git没有加入到环境变量中，会获取不到该值。知道了原理，那解决方式就自己想了，我这里就直接写死，上面这个方法直接返回固定字符串。

3.在build.gradle这里配置旧的apk和新apk:

def bakPath = file("${buildDir}/bakApk/")这个path可以改的:

ext {
    //for some reason, you may want to ignore tinkerBuild, such as instant run debug build?
    tinkerEnabled = true

    //for normal build
    //old apk file to build patch apk
    tinkerOldApkPath = "${bakPath}/app-debug-0519-10-42-25.apk"
    //proguard mapping file to build patch apk
    tinkerApplyMappingPath = "${bakPath}/app-debug-0519-10-47-45-mapping.txt"
    //resource R.txt to build patch apk, must input if there is resource changed
    tinkerApplyResourcePath = "${bakPath}/app-debug-0519-10-47-45-R.txt"

    //only use for build all flavor, if not, just ignore this field
    tinkerBuildFlavorDirectory = "${bakPath}/app-1018-17-32-47"
}

目前这个path是android studio上的

4.生成patch_signed_7zip.apk:

修改代码或是布局文件后，点击android studio右侧gradle按钮:

双击tinkerPatchDebug,然后会在

生成这个文件

5.然后apply path是:

TinkerInstaller.onReceiveUpgradePatch(getApplicationContext(), Environment.getExternalStorageDirectory().getAbsolutePath() + "/patch_signed_7zip.apk");

把patch_signed_7zip.apk放在这个目录下，然后执行上一句，就可以apply path了
