I am currently implementing my first Android app. Debugging and developing goes usually fine but sometimes I have problem when doing some changes in my code and then starting the app again from Eclipse environment (to virtual device).
As far as I understand it, new start terminates the currently running version of my app in the emulator, that's fine - but is this some correct termination? Is some event raised in my app which I should handle?
Why am I asking? My problem is that for most of the Activities being currently active in the emulator my app terminates (it's gone) correctly and new version starts fine. But for about 2 of my Activities when they are active and I "restart" my app from Eclipse I can see for a few seconds message box "Unfortunately APP has stopped" and that gives me an idea that these Activities have probably to do something in their destructor, uninitialize something or whatever because termination causes some kind of crash. How to detect this, how to debug this? When I start the app again, the old version debugger is disconnected so it's not helping. All I can see is logcat exception call stack info but it's not helping me too much:

Debugger problem, app terminated in bad way, not real issue.
Hello everybody,
I am developing a app which will download all the events from google calendar to android device.
I found this example:
http://code.google.com/p/google-api-java-client/source/browse/calendar-android-sample/?repo=samples
I also downloaded the required library from http://code.google.com/p/google-api-java-client/wiki/APIs
Also from here : "http://code.google.com/p/google-api-java-client/downloads/list"
But I am getting error as class definition not found. Please help me.
My Logcat is as follows:

I feel the issue is either database instance or any other object became null but you are calling some method using that object. Always check for null before using any methods of any object. see the sample example
example
if(database != null){
database.close();
}
Looks similar to this issue: SQLiteDatabase close() function causing NullPointerException when multiple threads
You may not need to call database.close()

I see the same verify error on both but I can't figure it out. The only common library used between the 2 apps is the FlurryAgent.jar for analytics.
For the top app I have
For the bottom app I have
in the manifests. The only information I have been able to find out is about libraries (GSON) and needing to use dx but I am using Eclipse so that doesn't help.
To make this more difficult, the error does NOT occur on the Android Market. Yet the testers at Amazon say that it FC 5/5 times on each of their devices (I tried using an emulator for their test devices and they worked fine). I know they use "wrapper" code around my app and I think it must be interfering in some way.
Does anyone have any experience with this?
I had a similar problem - resolved it by removing the non activity class from AndroidManifest.xml
Amazon injects their own code into your apps Activities life-cycle events. Knowing that and looking at the log you've provided:
10-12 15:41:50.359 W/dalvikvm( 2644): VFY: Lcom/companionfree/pushup/WorkoutDbAdapter; is not instance of Landroid/app/Activity;
It appears that Amazon's code tried to instrument a class (WorkoutDbAdapter) which is NOT an Activity (doesn't extends Activity), ending up being rejected by the JVM's verifier.
With my app this happened since the class was listed was listed an an Activity on AndroidManifest.xml. Removing this listing from AndroidManifest.xml resolved the issue and the app was admitted to the market.
Sarp wrote that renaming your class' packaged solved the issue, perhaps by doing so you've made your listing on AndroidManifest.xml no longer relevant. Thereby circumventing the problem.
I'd say this is the problem of the Amazon. Apparently they are injecting some DRM code into your apk: Injecting code into APK
Other people are seeing similar errors - Android app issue (Amazon)
In my case, the class that was causing a VerifyError was in a package called util. It was probably clashing with an injected package by Amazon, because renaming it to utils solved the problem.
Because our app was using Facebook SDK, it was given a "No, I will sign my binary" option when uploading a new binary. When you upload an unsigned APK this way, Amazon will let you download the processed binary (that includes their injected code) as Step 2 so that you can sign it. I was able to download a copy of my APK that crashes, and test my changes without going through the approval process this way.
I just solved my problem and may help to you
I just update the AS to 2.0 and ADT, and the verify issue come out
finally, be careful with the constructor like:
class abc {
abc(int x) {
....
}
abc(byte x) {
....
}
}
Hi all I have looked at the tutorial for creating tab layout on android on here:
link
which didn't work so I looked on here to find that there where errors with it. So I applied these and still I'm not getting anywhere with it.
The app loads on 2.1 emulator on eclipse and also on my phone but the application force closes each time which leads me to think that its a manifest problem.
Here is my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.Android.fitnessap"
android:versionCode="1"
android:versionName="1.0">

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

</manifest>
I've been stuck on this for hours now.
Thanks.

for a template on tabview that will work out of the box. Your manifest seems ok (but I'm not that good at android yet), so I would suggest using logcat to figure out what's up. In Eclipse, Window > Show View > Other.. and Under Android select logcat. Now run your app again and watch the ouptut of logcat for errors. It is a very good way to debug your app, just look for red exceptions and follow the ones related to your source code.
