Android系统应用默认权限设置

frameworks/base/services/core/java/com/android/server/pm/DefaultPermissionGrantPolicy.java 类是对默认权限管理类

我们可以通过此类来对我们系统中存在的应用进行默认权限设置。
下面举个例子，修改系统中应用存储空间权限：

    private void grantDefaultSystemHandlerPermissions(int userId) {
        ...
        grantStoragePermissionsToCustomApp(userId)；// add 
        ...
    }

private void grantStoragePermissionsToCustomApp(int userId){
    final String []itemString = mService.mContext.getResources()
        .getStringArray(com.android.internal.R.array.storage_permission_custom_packagename);
    for (int i = 0; i < itemString.length; i++) {
        PackageParser.Package customPackage = getPackageLPr(itemString[i]);
        if ((customPackage != null) && doesPackageSupportRuntimePermissions(customPackage)) {
            grantRuntimePermissionsLPw(customPackage, STORAGE_PERMISSIONS, userId);
        }
    }
}

当然要通过一个xml文件讲我们需要默认打开的应用罗列

<?xml version="1.0" encoding="utf-8"?>
