Question

我正在处理一个需要READ_PHONE_STATE权限的小应用。我在manifest.xml上添加了权限请求

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mobile.stoq.stoqpay">
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.INTERNET" />
    <application
    ...

然而，在阅读时，我发现我必须向用户提出实际请求才能获得该权限，因此我尝试使用以下代码段进行操作

public class ValidationActivity extends AppCompatActivity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_validation);
        //TODO: Fix this permission request. It sort of works but not really
        int REQUEST_RPS = 0;
        if (ContextCompat.checkSelfPermission(ValidationActivity.this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(ValidationActivity.this, new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_RPS);
        }

        List<UserModel> listOfUser = StoneStart.init(this);

        if (listOfUser == null) {

            List<String> stoneCodeToActiveList = new ArrayList<>();
            String STONE_PRODUCTION_KEY = "846873720";
            stoneCodeToActiveList.add(STONE_PRODUCTION_KEY);

            ActiveApplicationProvider activeApplicationProvider = new ActiveApplicationProvider(this, stoneCodeToActiveList);
            activeApplicationProvider.setDialogMessage("Activating");
            activeApplicationProvider.setDialogTitle("Please wait");
            activeApplicationProvider.setWorkInBackground(false);
            activeApplicationProvider.setConnectionCallback(new StoneCallbackInterface() {
                public void onSuccess() {
                    Toast.makeText(getApplicationContext(), "Activation successful", Toast.LENGTH_SHORT).show();
                    continueApplication();
                }

                public void onError() {
                    Toast.makeText(getApplicationContext(), "Activation failed", Toast.LENGTH_SHORT).show();
                }
            });
            activeApplicationProvider.execute();
        } else {
            continueApplication();

        }
    }

    private void continueApplication() {

        int SPLASH_DISPLAY_LENGTH = 3500;
        new Handler().postDelayed(new Runnable() {
            public void run() {

                Intent mainIntent = new Intent(ValidationActivity.this, MainActivity.class);
                ValidationActivity.this.startActivity(mainIntent);
                ValidationActivity.this.finish();
            }
        }, SPLASH_DISPLAY_LENGTH);
    }
}

当我的应用程序运行时，它将崩溃或冻结，并且在我重新启动它之后，我拥有正确的权限，并且它运行良好。这就是logcat向我展示的内容：

我做错了什么？我该如何解决这个问题？

}); if (socketCallback) { socketCallback(socket); } }); };是异步的。它会立即将控制权返回给您。 您还没有权限。

将ActivityCompat.requestPermissions()调用后显示的所有内容移动到单独的方法（我将在此处调用ActivityCompat.requestPermissions()）。然后：

如果foo()表明您有权限，请致电checkSelfPermission()
如果foo()显示您没有权限，则在checkSelfPermission()方法中，如果您现在拥有该权限，请致电onRequestPermissionsResult()
如果在foo()中，您仍然没有权限（例如，用户拒绝了您的请求），请以某种方式处理
