today when I created a sample app "My Application" with all basic configuration like
compileSdkVersion 22
buildToolsVersion "26.0.1"
defaultConfig {
applicationId "com.development.av.myapplication"
minSdkVersion 21
targetSdkVersion 22
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
with just one activity displaying hello world text.
even, my manifest file don't have any permission.
when I run this app on my testing device. its running well. which is having android version... 5.1.1
Then I send this app to my another android device which is having android version 6.0 but this device is not opening this app. installation was successful. but when I open this app, it gives me error saying, image1
when I click on try to resolve it gives another screen with option clear data ...after clicking on it it gives me another screen "app info" screen as...
but I didn't understand what is the problem with my app? anyone please suggest...
my updated build configuration is as follows
compileSdkVersion 26
buildToolsVersion "26.0.1"
defaultConfig {
applicationId "com.development.av.myapplication"
minSdkVersion 21
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
