Answer 1

입니다 : 내 장치 (에이서 E330)를 응용 프로그램을 실행하면 내가이 로그 캣 오류를했습니다

로그를 더 자세히 읽어야합니다! > com.google -

API key not found. Check that <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml 

좀 더 명확하게 선을 설명 할 수는 ;-)

"com.google.android.maps.v2.API_KEY""com.google.android.maps.API_KEY"

;-)
