My application works fine on Android 4, 5 and 6, when I plug devices to computer. But when I get .apk file from app/build/outputs/apk directory and install it directly, application crashes on Android 4 on start. Only on Android 4. Why? And how to fix it?
Here is my manifest file:
<manifest package="ru.pussy_penetrator.chgk"
xmlns:android="http://schemas.android.com/apk/res/android">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity
android:name=".QuestionGridActivity"/>
<activity
android:name=".QuestionPagerActivity"/>
</application>
Disable the Instant Run and Build the APK. Instant Run uses the device cache to hot swap the changes you make in the project. Also it optimizes the code to run on the platform that your testing device has.
You can also generate Signed apk for distributing across all the supported Android versions
I developed an android app with android studio selectiong the lowest androis os version. i tested the app on my samsung s4 and it works correctly, now i tested the same apk file on another device (LG g2) and when i open the app it close immediately. my app is very simple and i don't think to have used high version library, so i wanted to know if it was possible to compile my application for that specific device (LG g2) so that my app works on that phone (android 4.4.2). if not possible does someone know why that error?
this is manifest code

it seems that you are missing the intent filter. at least you didnt post it. can you have a look that you have the MAIN LAUNCHER like here? you need exactly one activity that matches this, if you want to be started from a homescreen.
<activity
android:name="..."
android:label="#string/app_name"
android:theme="#style/AppTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
I have installed a new setup of adb-bundle. When I run the project apk installed on device/emulator but not opens automatically. This problem is not related to coding I this it is related to eclipse setup because it happens with all projects. Please Help. Facing issue with debugging due to this problem.
Manifest.xml:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.demo.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>
</application>
Thanks
It seems like you have a problem with the adb. Open task manager and kill the adb process and restart everything and try again. If you have made some changes to the installed adb try to install it again properly.

Android application doesn't start from Eclipse
I am testing my app in Samsung Galaxy S2 with Android 2.3.4
I am following
http://developer.android.com/guide/topics/usb/accessory.html
instructions.
When ever I try to run it, usbManager.getAcccessoryList(); giving null.
Even I tried by connecting OTG cabel and pendrive to it.

I had the same problem but my tablet has ICS. If try what I did, might work. I've been searching a lot for this, and couldn't find it, but thanks to all the people who have spent a few moments answering our questions, and the wiki resources on the web, I figured it out.
There are some missing files in some android builds, like the AINOL NOVO 7 PALADIN. I think this would work in any ICS tablet with the same issue. I understand that the Galaxy Tab has the same issue but as I don't have one I can't confirm this. If you do, let me know if it works for you.
So lets push the files in and see how it goes.
Copy some missing files into system drive:
$ adb remount
$ adb push AINOL_FIX/system/etc/permissions/android.hardware.usb.host.xml /system/etc/permissions
$ adb push AINOL_FIX/system/etc/permissions/android.hardware.usb.accessory.xml /system/etc/permissions
NOTE: If an error appears displaying Out of Memory, it's right and you must delete some files from system drive. I recommend some live wallpapers from system/app.
I understand that for writing system drive you should have root access, I already had it when I did this so if it doesn't work, root it.
You can get the files from android source builds or from a tablet where USB-HOST API is actually working. I got them from linaro's ICS build for pandaboard.
Now, you should try finding those files but for Gingerbread and you'll also need to push the
future.usb.accesory.jar into system/framework, if it isn't there already.
$ adb push AINOL_FIX/system/framework/com.android.future.usb.accessory.jar /system/framework
A cite from http://developer.android.com/guide/topics/usb/accessory.html: "Set the minimum SDK of the application to API Level 10 if you are using the add-on library or 12 if you are using the android.hardware.usb package."
You are using the android.hardware.usb package. So, you have to put the version to 12.
An error is found :-)
And don't forget to really change SDK version to 12, not only declare it!
Use com.android.future.usb package instead, according to docs.
