Android Broadcast Receiver wird nicht trigerred

Question

Ich versuche, alle eingehenden SMS in meiner Android-Anwendung zu lesen. Ich habe einen Broadcast-Empfänger geschrieben, um die Nachrichten zu lesen und die Berechtigungen dafür im AndroidManifest hinzugefügt zu haben. Ich erhalte die folgende Fehlermeldung:

android.content.ActivityNotFoundException: Kann nicht explizit Aktivitätsklasse finden {com.example.asus.otpclippr/com.example.asus.otpclippr.readerService}; Hast du diese Aktivität in deiner AndroidManifest.xml deklariert?

Dies ist die AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.example.asus.otpclippr"> 
<uses-permission-sdk-23 android:name="android.permission.BROADCAST_SMS"/> 
<uses-permission-sdk-23 android:name="android.permission.RECEIVE_SMS" /> 
<uses-permission-sdk-23 android:name="android.permission.SEND_SMS" /> 
<application 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:supportsRtl="true" 
    android:theme="@style/AppTheme"> 
    <activity android:name=".MainActivity"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
    <receiver android:name="com.example.asus.otpclippr.readerService" > 
     <intent-filter> 
      <action android:name="android.provider.Telephony.SMS_RECEIVED"  /> 
     </intent-filter> 
    </receiver> 
</application> 

Dies ist das MainActivity.java Paket com.example.asus.otpclippr;

import android.app.ActivityManager; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.content.pm.PackageManager; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.View; 
import android.widget.Button; 
import android.widget.CheckBox; 

public class MainActivity extends AppCompatActivity { 
    CheckBox copyClip, createNotif ; 
    Button btn ; 
    private BroadcastReceiver br ; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    copyClip = (CheckBox)findViewById(R.id.checkBox) ; 
    createNotif = (CheckBox)findViewById(R.id.checkBox2) ; 
    btn = (Button)findViewById(R.id.button) ; 
    btn.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      boolean res = false ; 
      res = isMyServiceRunning(readerService.class) ; 
      Intent intent = new  Intent(MainActivity.this,readerService.class) ; 
      //intent.setAction("android.provider.Telephony.SMS_RECEIVED") ; 
      intent.putExtra("flag1",copyClip.isChecked()); 
      intent.putExtra("flag2",createNotif.isChecked()) ; 
      Log.d("Checkpoint1","calling broadcast") ; 
      startActivity(intent); 
     } 
    }); 

} 

/*public boolean isMyServiceRunning(Class<?> serviceClass){ 
    ActivityManager activityManager = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE) ; 
    for(ActivityManager.RunningServiceInfo service : activityManager.getRunningServices(Integer.MAX_VALUE)){ 
     if(serviceClass.getName().equals(service.service.getClassName())){ 
      return true ; 
     } 
    } 
    return false ; 
    }*/ 
} 

Und das ist das BroadcastReceiver Paket com.example.asus.otpclippr;

import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.os.Build; 
import android.os.Bundle; 
import android.provider.Telephony; 
import android.telephony.SmsManager; 
import android.telephony.SmsMessage; 
import android.util.Log; 
import android.widget.Toast; 

/** 
* Created by ASUS on 27-12-2016. 
*/ 

public class readerService extends BroadcastReceiver { 
    SmsManager smsManager = SmsManager.getDefault() ; 
    String[] msg ; 
    @Override 
    public void onReceive(Context context, Intent intent) { 



    final Bundle bundle = intent.getExtras() ; 
    try{ 
     if(bundle!=null) { 
      SmsMessage smsMessage; 

      if (Build.VERSION.SDK_INT >= 19) { //KITKAT 
       SmsMessage[] msgs = Telephony.Sms.Intents.getMessagesFromIntent(intent); 
       smsMessage = msgs[0]; 
      } else { 
       Object pdus[] = (Object[]) bundle.get("pdus"); 
       smsMessage = SmsMessage.createFromPdu((byte[]) pdus[0]); 
      } 
      String message = smsMessage.getMessageBody() ; 
      String[] checks = new String[]{"OTP","Transaction","Password","key","card","txn"} ; 
      msg = message.split(" ") ; 
      Log.d("Message",message) ; 
      for(int i=0;i<checks.length;i++){ 
       if(message.contains(checks[i])){ 
        checkforOTP(context,message) ; 
        Log.d("Check2","Checking for OTP") ; 
        break; 
       } 
      } 

      /*final Object[] pdusObj = (Object[]) bundle.get("pdus"); 
      for (int i = 0; i < pdusObj.length; i++) { 

       SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]); 
       String phoneNumber = currentMessage.getDisplayOriginatingAddress(); 

       String senderNum = phoneNumber; 
       String message = currentMessage.getDisplayMessageBody(); 

       Log.d("SmsReceiver", "senderNum: " + senderNum + "; message: " + message); 
       String[] msg = message.split(" ") ; 
       Toast.makeText(context,message,Toast.LENGTH_SHORT).show(); 
       String[] checks = new String[] {"OTP","Transaction","Password","key","card"} ; 
       for(int j=0; j< checks.length; j++){ 
        if(message.contains(checks[j])){ 
         checkforOTP(message) ; 
         break; 
        } 
       } 
      }*/ 
     } 
    }catch (Exception e){ 
     e.printStackTrace(); 
    } 
} 

public void checkforOTP(Context context ,String message){ 
    int pos = message.indexOf("is") ; 
    String msg1 = message.substring(pos,message.length()) ; 
    String otp1 = msg1.split(" ")[0]; 
    String msg2 = message.substring(0,pos) ; 
    String[] tempA = msg2.split(" ") ; 
    String otp2 = tempA[tempA.length -1] ; 
    if(isValid(otp1)){ 
     Toast.makeText(context,"OTP is"+otp1,Toast.LENGTH_SHORT).show(); 
    } 
    else if(isValid(otp2)){ 
     Toast.makeText(context,"OTP is "+otp2,Toast.LENGTH_SHORT).show(); 
    } 
    else{ 
     Log.d("check3","Wrong call") ; 
    } 

} 

public boolean isValid(String x){ 
    if(!(x.length()==4 || x.length() ==6)){ 
     return false ; 
    } 
    if(x.matches("\\d+")){ 
     return true ; 
    } 
    return false ; 
} 
} 

Was ist der richtige Weg, um einen Broadcast-Receiver aus dem MainActivity anrufen Vielen Dank im Voraus

Answer 1

Sie dies in einem OnClickListener tun:

 Intent intent = new  Intent(MainActivity.this,readerService.class) ; 
     //intent.setAction("android.provider.Telephony.SMS_RECEIVED") ; 
     intent.putExtra("flag1",copyClip.isChecked()); 
     intent.putExtra("flag2",createNotif.isChecked()) ; 
     Log.d("Checkpoint1","calling broadcast") ; 
     startActivity(intent); 

Sie rufen startActivity() mit einem Intent das zielt auf eine BroadcastReceiver. readerService ist ein BroadcastReceiver, kein Activity. Dies kann nicht funktionieren.
