1.I was trying to pass an array of string from 1 activity to another but the application is giving “Application Stopped Unexpectedly”.I am new to android and I don’t know how to do it.
2.Can you please tell me how to tackle these runtime errors and how to use logcat I’ve no
idea?
Code Activity A:
private OnClickListener mylistener=new OnClickListener() {
@Override
public void onClick(View arg0) {
intent=new Intent(MsgSmsActivity.this,MsgSmsActivity2.class);
MsgSmsActivity.this.startActivity(intent);
intent.putExtra("bodyText", body);
intent.putExtra("numbersText", number);
}
};
Code Activity B:
String[] arr;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// TODO Auto-generated method stub
arr=new String[3];
arr=getIntent().getExtras().getStringArray("bodyText");
TextView tx=new TextView(this);
tx.setText(arr[0]);
setContentView(tx);
}
The “body” and “number” are string arrays.
Here is my LogCat:

arr is an array of Strings.tx.setText(arr); will give exception because setText is defined to accept CharSequence
If you want to set some text on the TextView, then first get the String from array using arr[index] and then set that String to the textview.
