Question

我面临着非常奇怪的问题。当我直接从项目的bin文件夹中复制APK并粘贴到手机SD卡中。并安装它，它工作正常。虽然我在项目中使用Android工具导出签名APK并将APK放入SD卡。它安装成功但没有运行。我不知道为什么会这样。我也是你在app中的progaurad。是app崩溃的原因吗？

这是logcat输出

请提前帮助和致谢。

Answer 1

我认为你使用了错误的程序。当progurad出现问题时，会出现这种问题。尝试使用此代码替换project.properties- 这是链接 - Progurad Code

希望这会对你有所帮助。

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 - Signed apk未在移动设备上运行
