API 28：BroadcastReceiver onReceive 从未执行

Question

我的 onReceive 从未执行过。我试过在线遵循指南，包括来自官方网站的指南。我正在虚拟 API 28 设备上进行测试。我知道一些 GUI 相关的代码可能是错误的，但我至少应该得到一个正确的日志输出？我错过了什么？

清单：

        </intent-filter>
    </receiver>
</application>

接收者，第一个Log.D甚至没有执行：

 public class SMSReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("MESS", intent.getAction());
        Bundle bundle = intent.getExtras();
        if (bundle != null) {
            SmsMessage[] msgs;
            String message;
            Object[] pdus = (Object[]) bundle.get("pdus");
            msgs = new SmsMessage[pdus.length];
            for (int i=0; i<msgs.length;i++) {
                msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i], bundle.getString("format"));
                message = msgs[i].getMessageBody();
                Log.d("MESS", message);
                ((EditText) LayoutInflater.from(context).inflate(R.layout.activity_main, null)
                        .findViewById(R.id.editText)).append(msgs[i].getDisplayOriginatingAddress()
                        + "\n" + message + "\n");
            }
            abortBroadcast();
        }
    }
}

主要：

 public class MainActivity extends AppCompatActivity {

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

        requestSmsPermission();
    }

    private void requestSmsPermission() {
        String permission = Manifest.permission.READ_SMS;
        int grant = ContextCompat.checkSelfPermission(this, permission);
        if (grant != PackageManager.PERMISSION_GRANTED) {
            String[] permission_list = new String[1];
            permission_list[0] = permission;
            ActivityCompat.requestPermissions(this, permission_list, 1);
        } else {
            Toast.makeText(this, "Permission granted", Toast.LENGTH_SHORT).show();
            Log.d("", "Permission granted");
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                           @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == 1) {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                requestSmsPermission();
            } else {
                Toast.makeText(this, "permission not granted", Toast.LENGTH_SHORT).show();
            }
        }

    }
}

Answer 1

尝试提高优先级以便您的应用首先接收短信，我会将其设置为最大值：

 <intent-filter android:priority="2147483647">

Answer 2

您的实际问题出在SMS 权限。您只请求 READ_SMS 用户的许可，而不是 RECEIVE_SMS 许可。您还必须授予此权限才能实现此目的。

Manifest.permission.RECEIVE_SMS

尝试添加这个：

ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS, Manifest.permission.RECEIVE_SMS}, 1);

看起来像：

private void requestSmsPermission() {
    String readSms = Manifest.permission.READ_SMS;
    String receiveSms = Manifest.permission.RECEIVE_SMS;

    int grant = ContextCompat.checkSelfPermission(this, readSms) + ContextCompat.checkSelfPermission(this, receiveSms);
    if (grant != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, new String[]{readSms, receiveSms}, 1);
    } else {
        Toast.makeText(this, "Permission granted", Toast.LENGTH_SHORT).show();
        Log.d("", "Permission granted");
    }
}
