Question

so here is another basic problem i’m having…my application crashes as i try to pass a string to another activity. i have tried a few ways but in vain. here’s the code

Main Activity named Main.java

package com.ammad.test;

import android.os.Bundle;
import android.os.Handler;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class Main extends Activity {

    TextView tv;
    Button b1;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv = (TextView) findViewById(R.id.tvShow);
        b1 = (Button) findViewById(R.id.bt1);
        b1.setOnClickListener(new View.OnClickListener() {

            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                Bundle basket = new Bundle();
                String myScore = "testing";
                basket.putString("key", myScore);
                Intent intent = new Intent(Main.this, Second.class);
                intent.putExtras(basket);
                startActivity(intent);


            }
        });


    }
}

Second class to which the data is passes named Second.java

package com.ammad.test;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class Second extends Activity{

    TextView tv;
    String getScore;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.second);
        tv= (TextView) findViewById(R.id.tvRes);
        Bundle gotBasket = getIntent().getExtras();
        getScore = gotBasket.getString("key");
        tv.setText(getScore);
    }

}

and finally the manifest file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.ammad.test"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".Main"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".Sec"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="com.ammad.test.SECS" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Answer 1

Seems to me your second activity is declared wrong in the manifest, as .Sec not .Second as would be expected – the log is probably showing a exception because the intent was invalid.
