Question

从https://github.com/katchsvartanian/voiceRecognition导入。每当我在Android版本上运行项目时，Kitkat LogCat会出现以下错误：

    JNI DETECTED ERROR IN APPLICATION: illegal class   name 'com.example.jni.FLACStreamEncoder'
    (should be of the form 'package/Class', [Lpackage/Class;' or '[[B')
    in call to FindClass
    from void com.example.jni.FLACStreamEncoder.init(java.lang.String, int, int, int)

在以下行显示错误：

    init(outfile, sample_rate, channels,  bits_per_sample)

在下面的函数中的FLACStreamEncoder.java中。

public FLACStreamEncoder(String outfile, int sample_rate, int channels,int bits_per_sample)
{
    init(outfile, sample_rate, channels, bits_per_sample);
}

并在FLACRecorder.java中：

mEncoder = new FLACStreamEncoder (mPath, sample_rate, mapped_channels,  mapped_format)

我的FLACStreamEncoder.cpp包含以下代码，我已更改：

    static char const * const FLACStreamEncoder_classname="com.example.jni.FLACStreamEncoder";

到

    static char const * const FLACStreamEncoder_classname="com/example/jni/FLACStreamEncoder";

当我在进行上述更改后运行代码并将光标移到错误上时

    jclass cls = env->FindClass(FLACStreamEncoder_classname);

它显示提示为“jclass和jclass不兼容”。我不是很擅长C ++。我的FLACStreamEncoder.cpp包含以下代码。

    ...
    static FLACStreamEncoder * get_encoder(JNIEnv * env, jobject obj)
    {
    assert(sizeof(jlong) >= sizeof(FLACStreamEncoder *));
    // Do the JNI dance for getting the mObject field
    jclass cls = env->FindClass(FLACStreamEncoder_classname);
    jfieldID object_field = env->GetFieldID(cls, FLACStreamEncoder_mObject,"J");
    jlong encoder_value = env->GetLongField(obj, object_field);

    env->DeleteLocalRef(cls);

    return reinterpret_cast<FLACStreamEncoder *>(encoder_value);
    }

    static void set_encoder(JNIEnv * env, jobject obj, FLACStreamEncoder *   encoder)
    {
    assert(sizeof(jlong) >= sizeof(FLACStreamEncoder *));

    // Do the JNI dance for setting the mObject field
    jlong encoder_value = reinterpret_cast<jlong>(encoder);
    jclass cls = env->FindClass(FLACStreamEncoder_classname);
    jfieldID object_field = env->GetFieldID(cls, FLACStreamEncoder_mObject,   "J");
    env->SetLongField(obj, object_field, encoder_value);
    env->DeleteLocalRef(cls);
    }
    ...

我已在链接android art runtime check_jni.cc error on package name之后进行了更改。

我想知道的是，即使在更改类路径后，为什么它会显示相同的错误？

 'com.example.jni.FLACStreamEncoder' to "com/example/jni/FLACStreamEncoder"

它仍然在LogCat中显示相同的错误。

适用于Android KitKat。我必须在Lollipop上运行它
