    <p>I'm practicing and trying to change the flashlight (torch) on the back of my HTC. But I get no camera access, I put in the manifest the following:</p> <blockquote> <pre><code>&lt;uses-permission android:name="android.permission.FLASHLIGHT" android:permissionGroup="android.permission-group.HARDWARE_CONTROLS" android:protectionLevel="normal"/&gt; &lt;uses-permission android:name="android.permission.CAMERA"/&gt; &lt;uses-feature android:name="android.hardware.camera.flash" /&gt; </code></pre> </blockquote> <p>It can be very simple and stupid, but google and StackOverflow didn't gave me a solution, so can anybody tell me what I'm doing wrong? This is my activity file:</p> <pre><code>import android.app.Activity; import android.content.Intent; import android.hardware.Camera; import android.hardware.Camera.Parameters; import android.os.Bundle; import android.widget.*; import android.view.View; import android.util.Log; import java.util.List; public class FlashlightActivity extends Activity { private Camera mCamera; /** Called when the activity is first created, just a titlescreen. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageButton titlescreen = (ImageButton)findViewById(R.id.titlescreen); titlescreen.setOnClickListener(new View.OnClickListener() { public void onClick(View v){ TurnFlashOff(); if (mCamera==null){ finish();} else { Intent go = new Intent(TurnMeOnFlashlightActivity.this,TMO_App.class); startActivity(go); } } }); Log.d("TurnMeOn", "startpage"); } private void TurnFlashOff(){ if(mCamera != null){ mCamera = Camera.open(); Parameters params = mCamera.getParameters(); List&lt;String&gt; flashModes = params.getSupportedFlashModes(); if (flashModes.contains(Parameters.FLASH_MODE_TORCH)) { params.setFlashMode(Parameters.FLASH_MODE_OFF); mCamera.setParameters(params); mCamera.release(); mCamera = null; } else { Toast.makeText(TurnMeOnFlashlightActivity.this, R.string.FlashNoSupport, Toast.LENGTH_LONG).show(); mCamera.release(); mCamera = null; } } else { Toast.makeText(TurnMeOnFlashlightActivity.this, R.string.FlashNoSupport, Toast.LENGTH_LONG).show(); } } } </code></pre>

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.
