1、权限管理机制Android Runtime Permission.
2、Application Permission Manage的功能，该功能应该就是基于AppOps（应用程序权限管理）实现
AppOpsService.java
当应用需要去检查某个权限的时候,会调用checkOp或者noteOp去读取/data/system/appops.xml里面对应的值。
4.常用的接口
接口在AppOpsManager.java中，但大部分只针对系统应用。
-
public int checkOp(String op, int uid, String packageName)
检查某个应用(packageName)是否具有某个权限(op) -
public int checkOpNoThrow(String op, int uid, String packageName)
同checkOp,但出错不会报异常,返回MODE_ERRORED -
public int noteOp(String op, int uid, String packageName)
检查某个应用(packageName)是否具有某个权限(op)，同时会做记录 -
public int noteOpNoThrow(String op, int uid, String packageName)
同checkOp,但出错不会报异常，返回MODE_ERRORED -
/* @hide /
public void setMode(int code, int uid, String packageName, int mode)
设置权限，code是权限的标识码，比如OP_READ_CONTACTS, mode是权限的状态，比如MODE_ALLOWED
android/frameworks/base/services/core/java/com/android/server/am/ActivityManagerService.java:2701: mAppOpsService = new AppOpsService(new File(systemDir, "appops.xml"), mHandler);
ContentProvider.java
//权限检查
/**
* Result from {@link #checkOp}, {@link #noteOp}, {@link #startOp}: the given caller is
* allowed to perform the given operation.
*/
public static final int MODE_ALLOWED = 0;
if (enforceWritePermission(callingPkg, uri, null) != AppOpsManager.MODE_ALLOWED) {
return 0;
}
private int enforceWritePermission(String callingPkg, Uri uri, IBinder callerToken)throws SecurityException {
final int mode = enforceWritePermissionInner(uri, callingPkg, callerToken);
if (mode != MODE_ALLOWED) {
return mode;
}
if (mWriteOp != AppOpsManager.OP_NONE) {
return mAppOpsManager.noteProxyOp(mWriteOp, callingPkg);
}
return AppOpsManager.MODE_ALLOWED;
}
添加如下代码：
AppOpsManager appOps = (AppOpsManager)getSystemService(APP_OPS_SERVICE);
ApplicationInfo info = getApplicationInfo();
int mode = appOps.checkOp(AppOpsManager.OP_WRITE_SMS, info.uid, info.processName);
if (mode != AppOpsManager.MODE_ALLOWED) {
Log.d(TAG,"xxx mode="+mode+",info.uid="+info.uid+",info.processName="+info.processName);
appOps.setMode(AppOpsManager.OP_WRITE_SMS, info.uid, info.processName, AppOpsManager.MODE_ALLOWED);
}
