Question

我正在为车载设备（Andriod 5.1.1）中的Xposed编写模块。

我无法将声音加载到SoundPool中。 Andriod Studio找到文件（当您单击Yu时，文件R.raw.back开始播放。带有Activity的测试程序可以正常工作。

我将文件back.ogg放置在res \ raw文件夹和文件夹资产中。两次下载均失败。另外，创建带有图片的自定义吐司时会出错

public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable {
    XC_MethodHook onCreate = new XC_MethodHook() {
        @SuppressLint({ "sendToast" })
        protected void afterHookedMethod(MethodHookParam param) throws Throwable {
            Log.d(BackView.TAG, "onCreate");
            microntekServer = (Service) param.thisObject;
            context = (Context) param.thisObject;
            try {
                AudioAttributes audioAttrib = new AudioAttributes.Builder().setUsage(AudioAttributes.USAGE_GAME)
                        .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION).build();
                sp = new SoundPool.Builder().setAudioAttributes(audioAttrib).setMaxStreams(MAX_STREAMS).build();

                sp.setOnLoadCompleteListener(new OnLoadCompleteListener() {
                    @Override
                    public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
                        soundLoad = true;
                        Log.d(TAG, "BackId=" + sampleId + ", status=" + status);
                    }
                });

                try {
                    AssetFileDescriptor afd = context.getAssets().openFd("back.ogg");
                    Log.d(TAG, "open");
                    soundIdBack = sp.load(afd, 1); <- 1 expample
                    Log.d(TAG, "OK");
                } catch (Exception e) {
                    Log.e(TAG, e.getMessage());
                }
                soundIdBack = sp.load(context, R.raw.back, 1); <- 2 expample
                Log.d(TAG, "sp load");
            } catch (Exception e) {
                Log.e(TAG, e.getMessage());
            }

        }
    };
    if (lpparam.packageName.equals(SERVICE_PACKAGE_NAME)) {
        Utils.setTag(TAG);
        Utils.readXposedMap();
        Log.d(TAG, SERVICE_PACKAGE_NAME + " hook START");
        Utils.findAndHookMethodCatch("android.microntek.service.MicrontekServer", lpparam.classLoader, "onCreate",
                onCreate);
        Log.d(TAG, SERVICE_PACKAGE_NAME + " hook OK");
    }
}

错误加载文件示例1：back.ogg错误加载文件示例2：尝试调用接口方法'java.lang.String 空对象引用上的java.lang.CharSequence.toString（）'

Xposed模块。在SoundPool中加载声音时出错
