本文探讨了如何为安卓应用增加默认的动态申请权限。主要流程包括系统读取xml文件，如frameworksaseservicescorejavacomandroidserverpmDefaultPermissionGrantPolicy.java中的grantDefaultSystemHandlerPermissions(int userId)方法以及参考frameworksasedataetcprivapp-permissions-platform.xml的配置。

给应用增加默认的动态申请权限，具体解析流程自己梳理，系统主要是去读取xml文件的权限

第一、在frameworks\base\services\core\java\com\android\server\pm\DefaultPermissionGrantPolicy.java

中的方法

private void grantDefaultSystemHandlerPermissions(int userId)

private void grantDefaultSystemHandlerPermissions(int userId) {
    Log.i(TAG, "Granting permissions to default platform handlers for user " + userId);
    final PackagesProvider locationPackagesProvider;
    ......
    
     synchronized (mService.mPackages) {
			//就是下面这里增加一个方法
			grantStoragePermissionsToCustomApp(userId);
            // Installer
            PackageParser.Package installerPackage = getSystemPackageLPr(
                    mService.mRequiredInstallerPackage);
            if (installerPackage != null
                    && doesPackageSupportRuntimePermissions(installerPackage)) {
                grantRuntimePermissionsLPw(installerPackage, STORAGE_PERMISSIONS, true, userId);
            }

    ......
}

private void grantStoragePermissionsToCustomApp(int userId){
        final String []itemString = {"com.tencent.qq"};
        for (int i = 0; i < itemString.length; i++) {
            PackageParser.Package customPackage = getPackageLPr(itemString[i]);
            if ((customPackage != null) && doesPackageSupportRuntimePermissions(customPackage)) {
				grantRuntimePermissionsLPw(customPackage, MICROPHONE_PERMISSIONS, userId);
                grantRuntimePermissionsLPw(customPackage, STORAGE_PERMISSIONS, userId);
                grantRuntimePermissionsLPw(customPackage, CONTACTS_PERMISSIONS, userId);
                grantRuntimePermissionsLPw(customPackage, LOCATION_PERMISSIONS,true, userId);
                grantRuntimePermissionsLPw(customPackage, PHONE_PERMISSIONS, userId);
                grantRuntimePermissionsLPw(customPackage, CAMERA_PERMISSIONS, userId);
            }
        }
    }

第二、这里也要加上

frameworks\base\data\etc\privapp-permissions-platform.xml

<privapp-permissions package="com.tencent.qq">
		<permission name="android.permission.CAMERA"/>
        <permission name="android.permission.READ_CONTACTS"/>
        <permission name="android.permission.ACCESS_FINE_LOCATION"/>
        <permission name="android.permission.RECORD_AUDIO"/>
        <permission name="android.permission.READ_PHONE_STATE"/>
        <permission name="android.permission.WRITE_EXTERNAL_STORAGE"/>
        <permission name="android.permission.SEND_SMS"/>
</privapp-permissions>
