相同的代码在发布模式下不起作用(android 共享菜单)
Same codes do not work in release mode (android share menu)
以下代码在调试模式下完美运行:
menu_post_view.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context="com.mydream.bgz.activities.PostViewActivity">
<item
android:id="@+id/action_share"
android:title="@string/action_share"
app:actionProviderClass="android.support.v7.widget.ShareActionProvider"
app:showAsAction="always"/>
</menu>
PostViewActivity.java
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_post_view, menu);
ShareActionProvider mShareActionProvider;
MenuItem item = menu.findItem(R.id.action_share);
mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(item);
// mShareActionProvider.setOnShareTargetSelectedListener(this);
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
sharingIntent.putExtra(Intent.EXTRA_SUBJECT, str_mPostTitle);
sharingIntent.putExtra(Intent.EXTRA_TEXT, str_mPostUrl);
mShareActionProvider.setShareIntent(sharingIntent);
return super.onCreateOptionsMenu(menu);
}
一切都发生在onCreate()
方法中。我用 try-catch
包围了我的所有代码,并得到了以下打印的堆栈跟踪。

我从来没有遇到过这样的问题。所以,我不明白为什么一些 normal 代码在发布模式下不起作用,但调试构建版本。请注意,我没有在 onCreate()
中编写任何 与共享操作菜单相关的 代码。再次请帮助我了解为什么会出现此问题以及如何解决?
那是因为您在发布模式下混淆了代码。
将此添加到您的混淆器配置文件中。
-keep class android.support.v7.internal.** { *; }
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.internal.** { *; }
-keep interface android.support.v7.** { *; }
您可以在 proguard 配置中添加它。
-keep class android.support.** { *; }
-dontwarn android.support.**
-dontnote android.support.**
你可以在你的日志中看到这一行
java.lang.NullPointerException: 尝试在空对象引用
上调用虚拟方法'void android.support.v7.widget.bf.a(android.content.Intent)'
因为原码被混淆了,所以我们应该在proguard中设置不混淆这个文件
