I made a simple app for android and it works fine, however when I open an activity with adb the emulator displays a complete with dialogue: Complete action using __.
Does anyone know how to fix this?
It's just asking you how you want to run your API. Just select API Demos and "Always". It won't ask you again.
The problem was that because I moved the activity classes to another package, the old package info remained in gradle.build and in the android manifest.
Adb did not say that such an activity does not exist because I had a space in between the package name and activity name and it started some other application apparently.

I am working on a Google glass Android app. I have installed the glass development kit (GDK) in Android SDK. Now I created a glass project using Android Studio (Version 3.3.2). The newly created project is showing an error "Default Activity not found" in run->edit configuration.
Please refer the screenshot for the error.
1.
And 2. By clicking run->Edit Configuration in menu.
I have searched a lot on Google and found many articles regarding the same. All are suggested to set the edit configurations option like below.
Module: app
Package: Deploy default APK
Activity: Launch default Activity
Target Device: USB Device
I did the same, but no one is working for me. After spending the whole day to make it work, I came here. This error is due to the Launcher activity, because there is no launcher activity in Google glass project instead it uses Voice Trigger intent filter. It is similar to wearable apps they also don't have the launcher activity.
Android Studio won't let you use a standard run configuration without specifying a launcher in the manifest.
You could try using the gradle command line instead:
./gradlew installDebug
In case you haven't resolved the issue. I came across similar issue before, two ways worked for me:
Choose "Nothing" as the option. You will be able to run the app manually on the Glass, but your debugger won't work straight away. You have to manually attach the debugger to the process. You may also have to use logcat if there is a bug in the launching process.
Specify an activity (whichever is associated with voice trigger).
Also, I noticed that you created the app using Kotlin. Kotlin activity didn't work in my case, throwing exceptions associated with nullable var when resuming the activity. Non-activity classes worked fine. Please let me know if Kotlin activity worked in your case.
I am following a tutorial on creating a custom keyboard for an Android device. I am using Android Studio 2.1.2. There is no activity in the program because you have to activate the keyboard in the language & input settings.
When I run the program I get this error: "Could not identify launch activity: Default Activity not found
Error while Launching activity"
I have posted on the site but have gotten no response. I followed the tutorial step by step and looked it over for a couple of days. I am new to Android Studio and Android applications and was wondering if anyone knew how to help me.
This is the link to the site I am following: http://code.tutsplus.com/tutorials/create-a-custom-keyboard-on-android--cms-22615
I just figured out what needed to be done.
You have to edit the configurations and change the launch option to "nothing". This way it won't try to launch and activity that does not exist.
run->edit configurations then look for the launch options
Well you have answered it by yourself.
If you are creating an keyboard application(inputmethod) in android, everytime you compile and run your applcation, it will show a warning that there is no default activity since it's InputMethodService, the service. Even you add activity like some settings activity for your keyboard, it will still show you warnings and it's the normal operation.
In my program's any activity ,I press the home button,and then in desktop press my app's icon,I saw the launch activity,not before activity.What happen on my app?
And I found if I use Android Studio run without sign,the app is run normally.A month ago,I move the codes from eclipse to AS,on eclipse IDE not found this problem.Can anybody help me? Very thx.
Maybe grammar errors,sorry.
EDIT:I found this is an Android bug https://code.google.com/p/android/issues/detail?id=26658
And the solution is https://code.google.com/p/android/issues/detail?id=26658#c14
If you are working on real device, make sure you didn't set the flag
Don't keep activities in Developer options.
On emulator check in running configurations that you launch the default activity.
On manifest check that you do not exclude your activities from recent.
I'm using Eclipse and android SDK (with ADT Plugin), I don't know if it's some kind of configuration issue or it's some code problem. Whenever I load an app that I made from scratch (this means not using another existing code or one sample from the library) to my device or run it on the emulator, the entire app will load as "separate" apps, which are the activities. For example, if the app is named "Hello world" and it has two activities, "MainActivity" and "SecondaryActivity", both of them will show up on the device with their names as app names and sharing the app icon on the menu. Now, if I go to settings, "Hello World" appears as an application, now behaving again like it should. This doesn't affect the operation of the app, however, it's annoying to have more than 1 icon launching the same app. The problem is that, when i first used eclipse, this was not happening.
Just in case it helps, I've already re-installed the entire android SDK and the ADT plugin, as well, I tried using 3 different Eclipse versions (classic, EE, and Java developers), none of them seem to work, even though, in the Graphical Layout for any activity, the name of the app is showed in the bar with the app's icon, but running on the emulator or a real device it shows the activity's name there instead. I've looked everywhere and I haven't solved the problem.
Thanks!
Check your manifest to see if more than one activity has this:
<category android:name="android.intent.category.LAUNCHER" />
The answer I found for the above problem is, replace category.LAUNCHER to category.EMBED in all the activities apart from the MainActivity in your manifest file.
while i compile my application on sdk and on my phone i see the same application 3 times over the phone. Only 1 of them works and the other 2 throws exeption. this is the printscreen of the problem.
That sounds very much like you've marked all the activities in your application with categor android.intent.category.LAUNCHER --- that's what makes the activities show up in the launcher. Naturally, if one of your activities gets launched when it's not expecting to be, it'll likely crash. But you'll have to post more info (like a stack trace) to tell for sure.
When working on an emulator, you can choose to wipe all user data on boot from the AVD manager. You might want to give that a try.
Also, as Kartik said, if you changed the package name of the application, it will install alongside the previous versions as Android sees it as a new application and not as an upgrade.
