I want to block incoming SMS message as long as my application is running . I could achieve that but the problem is after I close the app or even restart or even uninstall it the user will not be able to receive SMS message anymore . So How can I make the application to block incoming SMS only when it's running and when it gets closed or uninstalled etc.. to stop blocking SMS. Here's my code :
BroadCastReceiver.Java
package com.example.sms;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;
public class BroadCastReceiver extends BroadcastReceiver
{
public void onReceive(Context context, Intent intent)
{
abortBroadcast();
}
}
MainActivity.java
package com.example.sms;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
Manifiest :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.sms"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<receiver android:name=".BroadCastReceiver">
<intent-filter android:priority="2147483647">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
<activity
android:name="com.example.sms.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Note: I've tested the application on android 2.2 on my android emulator "Sent SMS messages using Telnet"

Check if your app is running then only abort broadcast receiver else not
//define this variable above onReceive() with default value as false;
boolean appRunningInBack=false;
ActivityManager am = (ActivityManager) mContext.getSystemService(Activity.ACTIVITY_SERVICE);
String packageName = am.getRunningTasks(1).get(0).topActivity.getPackageName();
if(packageName.equalIgnoreCase("your app package name") || appRunningInBack)
{
appRunningInBack=true;
abortBroadCast();
} else {
}
Also add Permission in AndroidManifest.xml
<uses-permission android:name="android.permission.GET_TASKS" />
After this when your app goes in background.or while running .this variable will be true.
