我无法为ffmpeg调用Android java库的某些方法。我想我successfuly加载库，因为我可以CONSOLE.LOG库对象：如何在Nativescript中实现Java方法？
JS: BuildConfig -> function() { [native code] }
JS: ExecuteBinaryResponseHandler -> function() { [native code] }
JS: FFmpeg -> function() { [native code] }
JS: FFmpegExecuteResponseHandler -> function() { [native code] }
JS: FFmpegLoadBinaryResponseHandler -> function() { [native code] }
JS: LoadBinaryResponseHandler -> function() { [native code] }
这是多远我得到了（using this nativescript guide）：
// [...]
var MyCustomLoadBinaryResponseHandler =
com.github.hiteshsondhi88.libffmpeg
.LoadBinaryResponseHandler.extend({
onStart: function() {
console.log('Started loading ffmpeg');
},
onFailure: function() {
console.log('Failed loading ffmpeg');
},
onSuccess: function() {
console.log('Successfully loaded ffmpeg');
},
onFinish: function() {
console.log('Finished loading ffmpeg');
}
});
console.dir(MyCustomLoadBinaryResponseHandler);
//^ this logs the following
//~ JS: === dump(): dumping members ===
//~ JS: "()function() { [native code] }"
//~ JS: === dump(): dumping function and properties names ===
//~ JS: extend()
//~ JS: null()
//~ JS: === dump(): finished ===
var context = app.android.context;
var ffmpeg =
com.github.hiteshsondhi88.libffmpeg.FFmpeg.getInstance(context);
console.dir(ffmpeg);
//^ this logs the following
//~ JS: === dump(): dumping members ===
//~ JS: {
//~ JS: "constructor": "constructor()function() { [native code]
//}"
//~ JS: }
//~ JS: === dump(): dumping function and properties names ===
//~ JS: constructor()
//~ JS: concatenate()
//~ JS: execute()
//~ JS: getDeviceFFmpegVersion()
//~ JS: getLibraryFFmpegVersion()
//~ JS: isFFmpegCommandRunning()
//~ JS: killRunningProcesses()
//~ JS: loadBinary()
//~ JS: setTimeout()
//~ JS: <init>()
//~ JS: clone()
//~ JS: equals()
//~ JS: finalize()
//~ JS: getClass()
//~ JS: hashCode()
//~ JS: notify()
//~ JS: notifyAll()
//~ JS: toString()
//~ JS: wait()
//~ JS: === dump(): finished ===
ffmpeg.loadBinary(
new MyCustomLoadBinaryResponseHandler()
);
var MyCustomExecuteBinaryResponseHandler =
com.github.hiteshsondhi88.libffmpeg
.ExecuteBinaryResponseHandler.extend({
onStart: function() {
console.log('Started running ffmpeg');
},
onProgress: function(thisMessage) {
console.log(' ffmpeg running');
console.log(thisMessage);
},
onFailure: function(thisMessage) {
console.log('Failed running ffmpeg');
console.log(thisMessage);
},
onSuccess: function(thisMessage) {
console.log('Successfully run ffmpeg');
console.log(thisMessage);
},
onFinish: function() {
console.log('Finished running ffmpeg');
}
});
//this is where it crashes
ffmpeg.execute('-version', new
MyCustomExecuteBinaryResponseHandler());不幸的是，整个应用程序崩溃，没有错误信息的应用程序，我不能连续除非我有更多关于正在发生的事情的信息。我是否以错误的方式实施了这些方法？你如何建议我继续？

如果您没有看到错误的活动，那么它是一个JNI除外，它只能在亚行logcat进行跟踪。但是，这可能会在nativescript论坛中找到更好的答案。另外，共享可以复制问题的存储库将是理想的。 – pkanev
实际上，在控制台上有特定消息，JNI例外可能如您所建议的那样？我将它们包含在 –
