    <p>I'm having a problem that can not solve. I would like your help.</p> <p>I have an ImageButton that is calling another class, which is not the MainActivity. When I compile the program does not display any error but when I run the emulator and click on ImageButton he gives the following error:</p> <p>"The invalid application INOV (process org.me.teste) has stopped unexpectedly. Please try again."</p> <p>Below is my MainActivity and my other class:</p> <pre><code>package org.me.teste; import android.app.Activity; import android.content.DialogInterface; import android.content.DialogInterface.OnClickListener; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.view.View; import android.widget.ImageButton; import android.widget.TableLayout; public class MainActivity extends Activity { private TableLayout myTableLayout; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TableLayout myTableLayout = (TableLayout)findViewById(R.id.myTableLayout); ImageButton i = (ImageButton)findViewById(R.id.refributton); i.setImageResource(R.drawable.imagem); i.setBackgroundDrawable(null); i.setAdjustViewBounds (true); i.setOnClickListener(new View.OnClickListener(){ public void onClick(View view) { Intent perirefri = new Intent(org.me.teste.MainActivity.this, PerifericosRefri.class); startActivity(perirefri); } }); } } </code></pre> <p>Follow my class:</p> <pre><code>package org.me.teste; import android.app.Activity; import android.os.Bundle; import android.widget.ImageButton; import android.widget.TableLayout; public class PerifericosRefri extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.perifericosrefri); TableLayout myTableLayout2 = (TableLayout)findViewById(R.id.myTableLayout2); ImageButton i3 = (ImageButton)findViewById(R.id.camerabutton); ImageButton i4 = (ImageButton)findViewById(R.id.barcodebutton); i3.setImageResource(R.drawable.imagem3); i3.setBackgroundDrawable(null); i3.setAdjustViewBounds (true); i4.setImageResource(R.drawable.imagem4); i4.setBackgroundDrawable(null); i4.setAdjustViewBounds (true); } } </code></pre> <p>I am Brazilian and if I made a clerical error, I apologize.</p> <p>Thanks for the help guys!</p>

    1. CODoes logcat give any more info? My guess is that it's a nullpointerexception somewhere, but it's impossible to tell without more info.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
