I can't find any answer that solves my problem. I am getting NoSuchMethodError. Anybody help me. I am using the latest version of Javacv library.

推荐答案

您必须保持你的本地方法（你已经做），以及来自本地code称为Java方法。

You have to keep your native methods (which you're already doing), as well as the Java methods called from native code.

您可以保留所有javacv和javacpp方法，像这样：

You can keep all javacv and javacpp methods like so:

-keep class com.googlecode.javacv.**{ *; }
-keepclassmembers class com.googlecode.javacv.** {
    <methods>;
}
-keep class com.googlecode.javacpp.**{ *; }
-keepclassmembers class com.googlecode.javacpp.** {
    <methods>;
}

另外，如果你想减少生成输出警告：

Also, if you want to cut down on warnings in the build output:

-dontwarn com.googlecode.javacv.**, com.googlecode.javacpp.**
-dontnote com.googlecode.javacv.**, com.googlecode.javacpp.**
