Android

Question

我遇到了一个很奇怪的问题。当我直接从项目的bin文件夹中复制APK并粘贴到移动phone SD卡中时。并安装它，它工作正常。虽然我从项目中的 Android 工具导出签名的 APK 并将 APK 放在 SD 卡中。它安装成功但未运行。我不知道为什么会这样。我也是你在应用程序中的progaurad。这是导致应用程序崩溃的原因吗？？

这是logcat输出

请帮助并提前致谢。

Answer 1

我认为您使用了错误的混淆器。当 progurad 出现问题时，就会出现此类问题。尝试用此代码替换您的 project.properties - 这是 link - Progurad Code

希望对您有所帮助。

Answer 2

add this code to proguard.txt

if you are using v4

 # support-v4
-dontwarn android.support.v4.**
-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-keep class android.support.v4.** { *; }

if you are using v7

# support-v7
-dontwarn android.support.v7.**
-keep class android.support.v7.internal.** { *; }
-keep interface android.support.v7.internal.** { *; }
-keep class android.support.v7.** { *; }

Android - 在移动设备中未签名的 apk 运行

Android - Signed apk not run in mobile device
