I am making app for phones, but I wan’t them to be usable on tablets. I don’t know why can’t. I use this in my android manifest file:
android:xlargeScreens=\
The problem is your minSdkVersion
.
The xlargeScreens
-attribute was introduced in API-Level 9. Since you specified that your application will probably run under API-Level 4, android can't find this attribute.
Change the minSdkVersion
-attribute to 11
and it should work.
The targetSdkVersion
-attribute, which you set to be 11
only indicates that the App was developed to target this version (so it's "recommended"), but the minSdkVersion
specifies the minimum API-Level, see here.
