Android Proguard:发布版本强制关闭 [英] Android Proguard: Release build Force Close

问题描述

我通过启用minifyEnabled属性生成了发布版本，当我尝试运行发布版本时，它会强制关闭并显示以下日志. 请帮我调试一下

I generated release build by enabling minifyEnabled property and when I try to run the release build, it force closes with following log. Please help me to debug it

java.lang.NullPointerException

这是我的方法onCreateOptionsMenu的代码

This is my code for method onCreateOptionsMenu

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);
    //Set up ShareActionProvider's default share intent
    MenuItem shareItem = menu.findItem(R.id.action_share_main);
    mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(shareItem);
    mShareActionProvider.setShareIntent(getDefaultIntent());

    return super.onCreateOptionsMenu(menu);
}

推荐答案

问题是ShareActionProvider被剥离/混淆，但支持库需要将其保持原样.

The problem is that ShareActionProvider is being stripped/obfuscated, but the support library needs it to remain as-is.

将此行添加到您的proguard配置中，并应设置为:

Add this line to your proguard configuration, and you should be set:

-keep class android.support.v7.widget.ShareActionProvider { *; }
