build.gradle in module have higher priority then AndrodiManifest.xml
Try this.
AndroidManifest.xml have code:
build.gradle have code:
Warning in AndroidManifest.xml:
Try this.
AndroidManifest.xml have code:
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="23" />
build.gradle have code:
defaultConfig {
applicationId "cz.okhelp.words"
minSdkVersion 9
targetSdkVersion 19
versionCode 107
versionName "1.0.7"
}
Warning in AndroidManifest.xml:
This targetSdkVersion value (23) is not used; it is always overridden by the value specified in the Gradle build script (19) less... (Ctrl+F1)
The value of (for example) minSdkVersion is only used if it is not specified in the build.gradle build scripts. When specified in the Gradle build scripts, the manifest value is ignored and can be misleading, so should be removed to avoid ambiguity.Editace: 2014-02-15 20:46:40
