I am having an error when trying to switch from one activity(com.intelligent.stocktrader.MyAccount) to another(com.intelligent.stocktrader.SharePerformanceDetails).What am I doing wrong? My code has no error.
Below is the log cat content:

E/AndroidRuntime(787): FATAL EXCEPTION: main E/AndroidRuntime(787): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.intelligent.stocktrader/com.intelligent.stocktrader.SharePerformanceDetails}: java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = org.achartengine.chart.LineChart) E/AndroidRuntime(787): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1955) E/AndroidRuntime(787): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1980)

The MyAccount activity onCreate where am switching activities

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_performance);
    //Bundle extras = getIntent().getExtras();
    //stock_name = extras.getString("stock");
    //new PerformanceDetails().execute();   
    LineGraph line=new LineGraph();
    Intent intent=line.getIntent(getApplicationContext());
    startActivity(intent);
}

The LineGraph class

public Intent getIntent(Context context){

    -----------
            -----------
    return intent;
}

The LineGraph class has a method that will return an intent.Tha is where the error is propagating from

post your code, there is something with the object that you put in your intent – Boris Mocialov
is your activity shareperformancedetails registered in your manifest? – karan
probably indicates that your class is not serializable. org.achartengine.chart.LineChart – AnhSirk Dasarp
Yes Karan the manifest is up to date. – mungaih pk
please post your manifest also – karan

That's because you Intent contain LineChart, which can't be serialized. You shound make LineChart implements from java.io.Serializable.

Use following code on onclick() it willl work-

Intent i = new Intent(getApplicationContext(), SecondScreen.class);
StartActivity(i);

To run our application you should enter your new activity in AndroidManifest.xml file. Add new Activity between tags:

<activity android:name=".NewActivityClassName"></activity>

Try this:

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_performance);
//Bundle extras = getIntent().getExtras();
//stock_name = extras.getString("stock");
//new PerformanceDetails().execute();   
LineGraph line=new LineGraph();
Intent intent=new Intent(getApplicationContext(),SharePerformanceDetails.class); // EDITED
startActivity(intent);

}
