android - 从 Activity 上下文外部调用 startActivity() 需要 FLAG_ACTIVITY_NEW_TASK 标志？ nabinbhandari/Android-权限库

Question

使用时

nabinbhandari/Android-Permissions library: Link

当我在 Android 设备 API 级别 > 20 上运行应用程序时出现错误

这是非 Activity 类。 MainApp.getmContext() 返回应用上下文:

String[] permissions = {Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION};
    Permissions.check(MainApp.getmContext(), permissions, null/*rationale*/, null/*options*/, new PermissionHandler() {
        @Override
        public void onGranted() {
            // do your task.
            Toast.makeText(MainApp.getmContext(), "Granted", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onDenied(Context context, ArrayList<String> deniedPermissions) {
            Toast.makeText(MainApp.getmContext(), "Denied", Toast.LENGTH_SHORT).show();
        }
    });

Permissions.check 行出现错误。

我们必须在权限参数中传递[您要在其上显示权限]上下文的 Activity :

public static void permissionGrant(Context mContext){
    String[] permissions = {Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION};
    Permissions.check(mContext, permissions, null/*rationale*/, null/*options*/, new PermissionHandler() {
        @Override
        public void onGranted() {
            // do your task.
            Toast.makeText(MainApp.getmContext(), "Granted", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onDenied(Context context, ArrayList<String> deniedPermissions) {
            Toast.makeText(MainApp.getmContext(), "Denied", Toast.LENGTH_SHORT).show();
        }
    });
}
