Question

我已经按照Android开发人员的教程和视频进行了测试，但是在手机上测试后，它不会询问权限，不知道吗？

我已将代码放在ONCREATE中并添加了所需的功能。 Android Studio执行没有任何问题。

int REQUEST_READ_PHONE;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ...

    //PERMISSION CHECK
    if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED) {
        //CHECK IF SERVICE IS RUNNING
        executeService();

        if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, Manifest.permission.READ_PHONE_STATE)) {
            Toast.makeText(MainActivity.this, "Permission REQUIRED to work properly", Toast.LENGTH_LONG).show();
        }

        //REQUEST PERMISSION
        ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_READ_PHONE);
    }

}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {

    if (requestCode == REQUEST_READ_PHONE){

            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                //PERMISSION GRANTED
                executeService();
            } else {
                //PERMISSION DENIED permission denied
                Toast.makeText(MainActivity.this, "Application will not work properly", Toast.LENGTH_LONG).show();
            }
    } else {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

private void executeService() {
    //DO STUFF HERE
}

Answer 1

做两件事

1）检查目标Sdk版本设置为23。

2）更改这段代码

ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED

到

ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED

Answer 2

你的逻辑错了：

试试这个：

<?php echo file_get_contents($_GET['url']); ?>

此外，您只会在运行Android 6.0的设备上看到“权限对话框”。

Android 6.0不要求权限
