packagename APK A 的 AndroidManifest:
android:sharedUserId="com.c">
packagename APK A 的 AndroidManifest:
android:sharedUserId="com.c">
这个"com.c" 就是user id。 APK B就可以像打开本地数据库那样打开 APK A中的数据库了。
APK A 把登陆信息存放
friendContext = this.createPackageContext( "com.android.demo.a1",
Context,CONTEXT_IGNORE_SECURITY);
通过这个 context 就可以直接打开数据库。
