How can I intercept an sms, append a string to it, and pass it on as usual in Android

So I have to intercept the sms part figured out, as you can see in my code below.
However I run into trouble after receiving the message.
I need help appending a String to the end of the message, and then passing it on as normal as if it were never manipulated.

Why no broadcast's received between two activities?

I don't know why my receiver does not receive any thing.
I want to send broadcast between two activities.
tv1 does not show "msg".
Here is the code
send:
Intent intent = new Intent(action);
intent.putExtra("msg", "a");
sendBroadcast(intent);
startActivity(new Intent(MainActivity.this,sec.class));
receiver:
IntentFilter intentFilter = new IntentFilter(MainActivity.action);
registerReceiver(receiver, intentFilter);
BroadcastReceiver receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
tv1.setText(intent.getExtras().getString("msg"));
}
};

You can implement like this:
package com.example.broadcastrecieverdemo;
import android.os.Bundle;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;

public class MainActivity extends Activity {
private InternalReciever internalReciever;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
internalReciever = new InternalReciever();
IntentFilter filter = new IntentFilter("kishan");
registerReceiver(internalReciever, filter);
findViewById(R.id.btnSendBroadcast).setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setAction("com.example.broadcastrecieverdemo.CUSTOM_INTENT");
sendBroadcast(intent);
}
});
findViewById(R.id.btnInternalSendBroadcast).setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setAction("kishan");
sendBroadcast(intent);
}
});
}
#Override
protected void onDestroy() {
unregisterReceiver(internalReciever);
super.onDestroy();
}
}
class InternalReciever extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Inernal Broadcast recieved",
Toast.LENGTH_SHORT).show();
}
}

There is no radio Button in the xml posted
But you have this
rb1.setOnCheckedChangeListener(new OnCheckedChangeListener() {
You are probably getting NullPointerException. If you don't want remove the above.
Also remove
implements OnCheckedChangeListener
and this
#Override
public void onCheckedChanged(CompoundButton arg0, boolean arg1) {
// TODO Auto-generated method stub
}

MyFirstApp send button error

I've gone through the MyFirstApp tutorial to the point where the app should run and when you press the send button a new screen should appear , but instead of a new screen appearing it crashes with the 'Unfortunately, MyFirstApp has stopped' message.
I'm new to app development so I need basic instructions.

Your callback for the Button called sendMessage while you declared sendmessage in xml.

Android battery level

I have a problem with an application that sends coordinates via SMS.
When I added the battery level, the application stopped working after catching the fix.
