我的Proguard和我的自定义VideoView为我的应用程序遇到麻烦.看来我的代码模糊我的视频视频问题.每当我尝试为视频设置OnPreparedListener时,我的应用程序崩溃.看到:
11-13 15:54:45.881 19428-19428/com.<REDACTED> E/AndroidRuntime﹕ FATAL EXCEPTION: main Process: com.<REDACTED>,PID: 19428 java.lang.NoSuchMethodError: No virtual method setOnPreparedListener(Landroid/media/MediaPlayer$e;)V in class Landroid/widget/VideoView; or its super classes (declaration of 'android.widget.VideoView' appears in /system/framework/framework.jar:classes2.dex) at com.<REDACTED>.ui.module.MHVideoPlayerModule.initializeVideoPlayer(MHVideoPlayerModule.java:174) at com.<REDACTED>.ui.module.MHVideoPlayerModule.initializeViewData(MHVideoPlayerModule.java:154) at com.<REDACTED>.ui.activity.MHVideoDetailActivity.a(MHVideoDetailActivity.java:198) at com.<REDACTED>.ui.activity.MHVideoDetailActivity.b(MHVideoDetailActivity.java:171) at com.<REDACTED>.ui.activity.MHVideoDetailActivity.a_(MHVideoDetailActivity.java:255) at com.<REDACTED>.service.f.al.b(MHVideoUrlTaskManager.java:131) at com.<REDACTED>.service.a.e.onPostExecute(MHAsyncServiceTask.java:194) at android.os.AsyncTask.finish(AsyncTask.java:632) at android.os.AsyncTask.access$600(AsyncTask.java:177) ...
我已经尝试将以下行添加到Proguard文件中,但是它们没有帮助.
-keep class com.<REDACTED>.ui.module.MHVideoPlayerModule { *; } -keep class android.widget.VideoView { *; }
编辑:这是proguard-project.txt文件:
# If your project uses WebView with JS,uncomment the following # and specify the fully qualified class name to the JavaScript interface # class: -keepclassmembers class com.<REDACTED>.common.JavaScriptInterface { public *; } # Google Play Services start # https://developer.android.com/google/play-services/setup.html -keep class * extends java.util.ListResourceBundle { protected Object[][] getContents(); } -keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable { public static final *** NULL; } -keepnames @com.google.android.gms.common.annotation.KeepName class * -keepclassmembernames class * { @com.google.android.gms.common.annotation.KeepName *; } -keepnames class * implements android.os.Parcelable { public static final ** CREATOR; } # Google Play Services end -dontwarn javax.jdo.** -dontwarn javax.naming.** -dontwarn com.google.api.client.googleapis.extensions.android.gms.** -dontwarn com.google.android.gms.** -dontwarn com.squareup.okhttp.** -keep public class android.net.http.SslError -keep public class android.webkit.WebViewClient -keep public class android.widget.VideoView -dontwarn android.webkit.WebView -dontwarn android.net.http.SslError -dontwarn android.webkit.WebViewClient -dontwarn android.media.MediaPlayer -dontwarn android.widget.VideoView -dontwarn org.bouncycastle.** -dontwarn org.apache.commons.codec.binary.Base64 -keepattributes SourceFile,LineNumberTable -printusage build/outputs/proguard/unused.txt -printconfiguration build/outputs/proguard/configuration.txt -libraryjars libs -keep class com.crashlytics.** { *; } -keep class io.fabric.** { *; } -keep class android.support.v4.app.** { *; } -keep interface android.support.v4.app.** { *; } -keep class com.facebook.** { *; } # New Relic start # https://docs.newrelic.com/docs/mobile-monitoring/mobile-monitoring-installation/android/installing-android-apps-gradle-android-studio#proguard -keep class com.newrelic.** { *; } -dontwarn com.newrelic.** -keepattributes Exceptions,Signature,InnerClasses # New Relic end -dontshrink
解决方法
看来你还提供了一个定制的android.media.MediaPlayer和/或android.media.MediaPlayer.OnPreparedListener实现:
java.lang.NoSuchMethodError: No virtual method setOnPreparedListener(Landroid/media/MediaPlayer$e;)V in class Landroid/widget/VideoView; or its super classes (declaration of ‘android.widget.VideoView’ appears in /system/framework/framework.jar:classes2.dex)
setOnPreparedListener – 您调用的方法
(L – 对象的smali前缀
android / media / MediaPlayer $e – 您尝试传入方法的实际类型名称.这就是问题.内部类型OnPreparedListener正在被模糊化.应该是android / media / MediaPlayer $OnPreparedListener
android / widget / VideoView尝试托管此方法签名的类.
你有一个自定义MediaPlayer或MediaPlayer.OnPreparedListener使用原始的包名称?如果是这样,您还需要从Proguard中排除这些.就像是:
-keep class android.media.** {*; }
