Android API 26 SecurityException 问题

Question

在我的应用程序中，我有一个片段和这个片段内的 imageButton。当我在我的设备 (Android 8 - API 26) 中运行应用程序并单击 imageButton 时，应用程序崩溃并引发我以前没有看到的运行时错误。

E/AndroidRuntime: FATAL EXCEPTION: main

所以我在 Manifest.xml 中添加了所需的权限，并尝试了主题 Android permission.INTERACT_ACROSS_USERS_FULL 中的每个代码，但我得到了同样的错误。我已经解决了这个主题的自动填充问题，但是只有我点击了 ImageButton 才会发生片段错误。我应该怎么做才能解决这个问题？

Answer 1

我终于找到了解决方案。出现问题是因为我的活动中有一个名为 getUserId() 的方法，该方法返回字符串 user_id 并将数据发送到片段。我更改了它的名称，现在一切正常。

Answer 2

您必须添加运行时权限。为此，请遵循

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                if (!checkIfAlreadyhavePermission()) {
                    requestForSpecificPermission();
                }
}

模块 checkIfAlreadyhavePermission() 实现为：

private boolean checkIfAlreadyhavePermission() {
    int result = ContextCompat.checkSelfPermission(this, Manifest.permission.INTERACT_ACROSS_USERS_FULL);
    return result == PackageManager.PERMISSION_GRANTED;
}

模块 requestForSpecificPermission() 实现为：

private void requestForSpecificPermission() {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.INTERACT_ACROSS_USERS_FULL}, 101);
}

并在 Activity 中覆盖：

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case 101:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                //DO WHATEVER YOU WANTED TO DO
            } else {
                //not granted
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}
