我的 Android 应用程序仅在不可调试时崩溃？

Question

我有一个 Android 应用程序在调试模式下运行良好，但在发布模式下开始出现问题。它在将项目绑定到回收站视图时崩溃。

最初我认为这将是一个 proguard 问题，但在为调试模式启用 proguard 后，很明显只有发布版本有这个问题。为了试一试，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 不可调试时才会导致崩溃？或者有什么方法可以调试它，看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'
    }
}

所以，如果我将debuggable true 添加到release，则发布版本可以工作。如果我将debuggable false 添加到debug，则调试版本将停止工作...

Answer 1

对我来说，问题是我正在测试发布版本并禁用 Crashlytics 以便不跟踪我的活动。 当“可调试”设置为 true 时工作正常，但一旦设置为 false，我在应用程序启动时收到即时崩溃。 所以基本上我忘记打开 Crashlytics 并从中得到一些内部错误。

Answer 2

正如@laalto 所说，有一个堆栈跟踪可能会有所帮助

把它放在我的 proguard 文件中：

-keepattributes SourceFile,LineNumberTable

帮助我找到错误所在。这将向您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不会发生错误，但至少我能够解决它。再次感谢！

Answer 3

如果您使用的是 C 重载函数，请不要使用！

IE A类

ofAndroidInit(){ 
  // will only work with debugging = false
}

B 类 main.cpp

ofAndroidInit() {
 // will work with debugging = true
}
