We can test the assumptions about “Developer Mode” by turning it off as explained in this article.
I’m got this error on the build and added the minSdkVersion to build.gradle in the openCVLibrary section. After the minor change to the gradle file, it builds.
ERROR: Manifest merger failed : uses-sdk:minSdkVersion 1 cannot be smaller than version 9 declared in library [com.android.support.test.espresso:espresso-core:3.0.1] /home/craig/.gradle/caches/transforms-2/files-2.1/52087f1a134c863438d388d5c643f3da/AndroidManifest.xml as the library might be using APIs not available in 1
Suggestion: use a compatible library with a minSdk of at most 1,
or increase this project's minSdk version to at least 9,
or use tools:overrideLibrary="android.support.test.espresso" to force usage (may lead to runtime failures)
