我正在做一个关于 sim 跟踪的应用程序，但无法获得结果

这是主要活动

public class MainActivity extends Activity {

String FILENAME = "old_file.txt";
int simstatus;
String simNo;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

     TelephonyManager tManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

        if (simstatus != TelephonyManager.SIM_STATE_ABSENT) {
            System.out.println("--------SIM Present:" + simstatus);
            simNo = tManager.getSimSerialNumber();
            FileOutputStream fos;
            try {
                fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
                fos.write(simNo.getBytes());
                System.out.println("---------Data written to files is:"
                        + simNo);
                fos.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
}

接收者

public class SimDataReciever extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction()))  {   
            System.out.println("Reciever Started");
            Intent CompareSimServiceIntent = new Intent(context,demo.class); 
            context.startService(CompareSimServiceIntent);  
        }
    }
}

和服务..

String FILENAME = "old_file.txt";

    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }

    public int onStartCommand(Intent intent, int flags, final int startId) {

         Timer timer = new Timer();
            timer.schedule(new TimerTask() {
                @Override
                public void run() {
                    //run your service

//                   Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
                    TelephonyManager tManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
                    try {
                        FileInputStream fis = openFileInput(FILENAME);
                        InputStreamReader in = new InputStreamReader(fis);
                        BufferedReader br = new BufferedReader(in);
                        String data = br.readLine();
                        System.out.println("---Data Read From File is:" + data);
                        String newsiminfo = tManager.getSimSerialNumber();
                        System.out.println("---New SIM no is:" + newsiminfo);
                        if (data.equals(tManager.getSimSerialNumber())) {
                            System.out.println("------Old sim Present:");
//                          Toast.makeText(this, "Old SIM", Toast.LENGTH_LONG).show();

                        } else {
//                          Toast.makeText(this, "New SIM", Toast.LENGTH_LONG).show();
                            SmsManager smsMngr = SmsManager.getDefault();
                            String destinationaddress = "8281306132";
                            String scAddress = null;
                            String text = "New Sim Is Inserted In Your Device";
                            PendingIntent sentIntent = null;
                            PendingIntent deliveryIntent = null;
                            smsMngr.sendTextMessage(destinationaddress, scAddress, text,
                                    sentIntent, deliveryIntent);
                            System.out.println("-----SMS Send");
                        }

                    } catch (Exception e) {

                    }
                }
            }, 1*60*1000);

        return startId;
    }

}

请帮助我找到解决方案....

在从事同类项目时，我发现了类似的问题。

设备重启后我也无法跟踪 sim。我在这里发现的问题是我在设备重启后立即调用了 sim 跟踪。但是系统加载资源需要 15 到 20 秒。设备重新启动后，SIM 卡没有立即启动，因此我的接收器无法跟踪 sim 卡。

因此，我在设备重启后将 sim 跟踪延迟了 20 秒。尝试延迟 sim 跟踪并检查它是否有效。

编辑- 您的接收器应该是这样的，

public class SimDataReciever extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
            System.out.println("Reciever Started");
            Log.d("BOOT COMPLETE","Receiver Called");
            Intent CompareSimServiceIntent = new Intent(context,demo.class); 
            context.startService(CompareSimServiceIntent);  
    }
}

并在清单文件中，用此替换您的代码，

    <receiver android:name=".SimDataReciever" 
         android:enabled="true" 
         android:exported="false">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED"/>
        </intent-filter>
    </receiver>

现在，检查消息是否显示在 logcat 中。
