Android应用程序崩溃与proguard规则

我的应用程序工作正常，没有应用保护规则，但出于安全目的，我必须在我的应用程序中应用保护规则。我在应用规则并尝试运行我的应用程序时遇到了这些错误。Android应用程序崩溃与proguard规则

从您的日志中可以清楚地看到崩溃发生在'MainActivity'中。确保你已经为你正在使用的所有图书馆添加了专业排除。检查您是否排除了在MainActivity中使用的库 –

@MuchOverflow我只在MainActivity中使用了Volley库。我应该排除哪些内容？你能给我个建议吗？ – DhavalThakor

检查这个帖子http://stackoverflow.com/questions/21816643/volley-seems-not-working-after-proguard-obfuscate – AndroidRuntimeException

好像你已经使用截击和使用ProGuard崩溃您的应用程序。您可以将此行写入您的proGuard。

-keep class org.apache.commons.logging.**
