I added myself as a tester for my Android app. Received and opened the email on my Android device. Got to this screen:
Clicked on "Download" and got this:
The problem now: The "INSTALL" button doesn't work, i.e., it's not clickable.
This was on Nexus 5X Android 7.0.
Make sure there aren't any apps drawing to the screen like screen dimming apps (see: https://android.stackexchange.com/questions/69981/why-cant-i-press-the-install-button-when-installing-applications-from-unknown-s).
I am making one lock application and for that I need to disable home button. I already tried all the common solutions available and it works for other android versions but for this device which is running on Android 4.2.2 it fails always.
You can't disable the home button as it can cause security issues promoting malicious apps etc.
What you can do is add an overlay to your app instead that will cover over other apps.
See this link for more info:How to disable Home and other system buttons in Android?
Make application as launcher.
First time when home button is pressed, device ask for choose launcher, select your applicaiton with always options.
From the next time when application is opened and you press the home button app never go in background.
Actions to reproduce bug:
Install APK (doesn't matter from market or eclipse or via usb connection) (
Do some stuff i.e. set cities, start search.
Press HOME button.
Open application launcher menu.
Press Aviascanner icon.
In some cases (about 5%) system starts new clean copy of application without selected cities and other data. If you press BACK button you can see previous copy of app (so it works in one task).
This behavior can be watched on this devices:
Samsung Galaxy Tab 2 10.1 OS 4.0.4
Samsung Gt-s6500d OS 2.3.6
I can't reproduce it in HTC Wildfire S A510e.
Also you can look at the youtube video where bug is reproduced (sorry for bad quality and russian language but the bug is very uncommonly, it was very hard to catch it)
Assuming that Step #2 is triggered by clicking "Open" from the post-install screen, or by running the app from Eclipse, this is a long-standing issue with Android.
This question outlines some options: How to prevent multiple instances of an activity when it is launched with different intents
I have developed an android application whose first version is already available on Google play.
Now my problem is, when I installed first version of my app on any android device (Samsung galaxy SII, LG Optimus), it works fine for me.
I have created shortcut of my app on home screen and have moved my app from phone memory to SDCard.
Then I have install new version of the same app on my phone and tried to open it from the shortcut that I have created on home screen.
But app is not opening from that shortcut and giving me an error message that "application is not installed on your device".
Does anybody have any idea why this happening?
Haven't you declared one of your activities or permissions twice by accident? You might have declared you launcher activity again somewhere in the Manifest.
I have an app in development that runs fine in the emulator but wont run on any android device, when the application icon is clicked the screen goes blank for a second then returns back to the device apps page, i have experimented with setting different permissions but it does not seem to solve the issue. Any ideas?
