我已经为我的应用构建了2个不同的APK文件，其中包含2个不同的包名com.xxx.digital（生产版）和com.xxx.digital.staging（暂存/测试版）
一旦我安装了2个APK中的一个，另一个的安装就失败了 怎么了？
build.gradle：
productFlavors {
staging {
applicationIdSuffix ".staging"
resValue "string", "app_name", "Staging"
}
production {
resValue "string", "app_name", "My App"
}
}
我尝试在同一台设备上安装com.xxx.digital.staging时首先安装了com.xxx.digital：

答案 0 :(得分：2)
内容URI是用于标识提供商来源中的数据的URI： google.deveoper.com
您正尝试在内容提供商中使用相同的内容权限构建两个不同的APK。
我建议的解决方案是使用 BuildConfig.APPLICATION_ID 作为 AUTHORITY ，这将在所有各种风格中有所不同。
<强> MySuggestionProvider
public class MySuggestionProvider extends SearchRecentSuggestionsProvider {
public final static String AUTHORITY =BuildConfig.APPLICATION_ID;
public final static int MODE = DATABASE_MODE_QUERIES;
public MySuggestionProvider() {
setupSuggestions(AUTHORITY, MODE);
}
}
答案 1 :(得分：1)
您似乎正在为应用程序使用不同的程序包名称，但内容提供程序仍具有相同的行李名称。那是不允许的。
