Question

我有一个Android应用程序，在调试模式下可以正常工作，但是在发布模式下开始出现问题。将项目绑定到recyclerview时崩溃。

最初，我认为这将是一个proguard问题，但是在为调试模式启用proguard之后，很明显只有发行版才存在此问题。只是尝试一下，我将发布版本设置为debuggable true，问题就消失了。

有没有人知道只有当apk无法调试时才可能导致崩溃的原因？或以任何方式调试它并查看到底出了什么问题？

这些是我的构建类型：

buildTypes {
    debug {
        multiDexEnabled true
        shrinkResources true
        minifyEnabled true
        useProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    release {
        multiDexEnabled true
        shrinkResources true
        minifyEnabled true
        useProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

因此，如果我将debuggable true添加到release，则发行版本有效。如果我将debuggable false添加到debug，调试版本将停止工作...

Answer 1

对我来说，问题在于我正在测试发行版，并禁用了Crashlytics，以使其无法跟踪我的活动。将“ debuggable”设置为true可以正常工作，但是一旦将其设置为false，我就会在应用启动时立即崩溃。所以基本上我忘了打开Crashlytics，并从中收到一些内部错误。

Answer 2

如@laalto所说，有一个堆栈跟踪可能会有所帮助

将其放入我的proguard文件中：

-keepattributes SourceFile,LineNumberTable

帮助我找到错误所在。这将显示堆栈跟踪中的原始类名和行号。我仍然不确定为什么调试模式下不会发生错误，但是至少我能够解决它。再次感谢！

我的Android应用仅在无法调试时崩溃？
