This is the result of my attempt to run the pilot project There is no output in logcat I checked the answers to other similar questions on so. They said it might be because of accented characters I don't have these

This is my simple code:

public class HaikuDisplay extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    public void onTrialButtonClicked(View view){
        TextView v = (TextView) findViewById(R.id.text);
        v.setVisibility(View.VISIBLE);
    }

}

This is XML:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".HaikuDisplay" >
    <Button 
        android:id="@+id/topBtn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/love_button_text"
        android:onClick="onTrialButtonClicked"
        />
    <TextView
        android:layout_below="@id/topBtn"
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" 
        android:visibility="invisible"/>

</RelativeLayout>

How can I solve it?

Solution

This error can point to many different things, and there are many different fixes Summarize what I collected:

>Eclipse issues: clean up projects, rebuild projects, restart eclipses. > Invalid characters: remove any special characters from the eclipse project name Use only [A-Z] and [0-9] and not even [] (spaces) > include errors in jars: try not to use jars and see if it works, if it does fix it in some way. > Error in manifest package settings: right click eclipse – > Android tools – > rename application package in the project (rename to something similar, you can always rename). > Device problem: remove the application from the device and try to reinstall. > ROM problem: if you try to refresh to a new ROM using a custom Rom. > debugging not enabled: on your phone go to settings – > applications – > allow unknown source / enable debugging (this path varies from device to device)
