my application has stopped unexpectedly in android please try again - android

I have an error in my android code:
case R.id.bSQLOpenView:
Intent i = new Intent("com.fps.say.SQLView");
startActivity(i);
break;

There are several possible ways to run an activity.
Here's the method I use:
Intent i = new Intent (this, YourTargetActivity.class);
startActivity(i);
The this corresponds to your current activity.
Using such a call gives you the convenience to have your IDE autocomplete the desired activity name.


Dubble check the name of the class
Dubble check the name which should be mentioned in the manifest file
Perform a clean-build


Intent i = new Intent(this,SQLVIEW.class);

android permission issue : apk not being accepted

I am submitting a new version of my app. But the developer console doesn't allow me to do so. It says that my app is not compliant with the new policies for the permission (ask for permission at runtime).
But as I can see, I don't use any dangerous permission...
My app is using the following permissions (according to the developer console) :
android.permission.ACCESS_NETWORK_STATE, android.permission.ACCESS_WIFI_STATE, android.permission.INTERNET, android.permission.WAKE_LOCK

Thanks in advance for your help.

To find where permissions might be originating, you can look at the merged manifest file using Android Studio. Open your manifest file in Android Studio and the click the "Merged" tab at the bottom of the editor. Here is a picture for context:

No Launcher Activity Found even though there is [duplicate]

This question already has answers here:
No Launcher activity found
(2 answers)
Closed 9 years ago.
This is a copy of my AndroidManifest.xml
Any help as to why the launcher is not being recognized? I tried running the code without applying DEFAULT to any other activity but it's still not working.
enter code here
<application
<activity
android:name="project.shirsho.Menu"
android:label="#string/app_name" >
<intent-filter>
<action android:name="project.shirsho.MENU" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="project.shirsho.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="project.shirsho.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name="project.shirsho.Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name="project.shirsho.Textplay"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.TEXTPLAY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>

You need to specify the MAIN and LAUNCHER in the the intent filter for the activity you want to start on launch by :
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
if you want that Splach Activity as your launcher , your manifest must be :
<application>
<activity
android:name="project.shirsho.Menu"
android:label="#string/app_name" >
</activity>
<activity
android:name="project.shirsho.MainActivity"
android:label="#string/app_name" >
</activity>
<activity
android:name="project.shirsho.Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name="project.shirsho.Textplay"
android:label="#string/app_name" >
</activity>
</application>

I believe that you are trying to make "project.shirsho.Menu" as the launcher activity, then it should be like:
<activity
android:name="project.shirsho.Menu"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
change,
<intent-filter>
<action android:name="project.shirsho.MENU" />
to
<intent-filter>
<action android:name="android.intent.action.MAIN" />
Hope this helps! :)

This is how your application part should look like. If you use eclipse to develop in it will help you create this (androidManifest.xml)
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SplashActivity"
android:label="#string/app_name" >
<intent-filter>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

Android No Launcher activity found

I am having this problem.
I created a new xml layout (splash screen) and in manifest set it as Launcher category.

These lines
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
should be present only in the main activity tag. Remove from all other activity tags.
Adding this intent filter indicates that this activity is the main activity of the app and should be listed in the launcher(apps drawer)

And I would add that the android:label should only be present on the application tag, not anywhere else.

Android app icon shows on device to allow uninstall but does not allow to execute

I am able to run an android app in two virtual devices when degugging.(Galaxy tab and phone). When I close the app in debug mode the icon is not showing in the virtual device.
The same thing occurs when I load a signed .apk file to the actual devices.
The app icon shows when I go into manage applications. I can uninstall the app. Thats all I can do. I cannot launch the app since the icon is not visible with the other app icons.
I am using platform 2.2 with google api's 8.
What am I doing wrong? How can I get the app icon to show with other apps and be able to launch?
Here is my manifest file.
Any help is appreciated.

You should only be using <category android:name="android.intent.category.LAUNCHER" /> for one of your activities, not all of them. Try removing all others except the one that goes with <action android:name="android.intent.action.Main" />
EDIT: I may be wrong but I think you'll also need to capitalize MAIN as in <action android:name="android.intent.action.MAIN" /> for it to be recognised as the 'main' entry point (main activity).

Try to remove "android.intent.category.LAUNCHER" for each activity because android project must have only one LAUNCHER activity.

try to this if your main activity use this
<intent-filter>
<action android:name="android.intent.action.Main" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Other activity you can use this
<intent-filter>
<action android:name="android.intent.action.(your action )" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
I think it can be helpful to you .
