Question

我通过启用minifyEnabled属性生成了版本构建，当我尝试运行版本构建时，它强制关闭以下日志。请帮我调试一下

java.lang.NullPointerException
        at MYPACKAGENAME.MainActivity.onCreateOptionsMenu(Unknown Source)
        at android.app.Activity.onCreatePanelMenu(Activity.java:2538)

这是方法onCreateOptionsMenu

的代码

@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);
}

问题是ShareActionProvider被剥离/混淆，但支持库需要它保持原样。

将此行添加到您的proguard配置中，您应该设置：

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

Android Proguard：发布build Force Close
