如何处理我的应用请求拨打和管理电话?

Question

我的应用需要用户接受弹出的"允许拨打和管理电话"。 如何在应用程序首次启动时弹出这些内容？

我已经在清单中添加了权限：

<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />

但弹出窗口中没有任何内容。

从 Android 6.0 开始，您必须提供运行时权限链接。

public  boolean isPermissionGranted() {
if (Build.VERSION.SDK_INT >= 23) {
if (checkSelfPermission(android.Manifest.permission.CALL_PHONE)
== PackageManager.PERMISSION_GRANTED) {
Log.v("TAG","Permission is granted");
return true;
} else {
Log.v("TAG","Permission is revoked");
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE}, 1);
return false;
}
}
else { //permission is automatically granted on sdk<23 upon installation
Log.v("TAG","Permission is granted");
return true;
}
}

@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case 1: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(getApplicationContext(), "Permission granted", Toast.LENGTH_SHORT).show();
call_action();
} else {
Toast.makeText(getApplicationContext(), "Permission denied", Toast.LENGTH_SHORT).show();
}
return;
}
// other 'case' lines to check for other
// permissions this app might request
}
}
