我正在尝试按照以下指南使用LAME库在Android中实现MP3编码： Lame MP3 Encoder for Android

http://developer.samsung.com/android/technical-docs/Porting-and-
using-LAME-MP3-on -Android-
JNI

但是我收到了java.lang.UnsatisfiedLinkError，我认为这可能是由于我的软件包名称包含一个下划线，它会将其解释为句号。

在下面的代码中可能会出现此问题，以及如何解决该问题。还是有其他原因造成这种情况。在此先感谢您的帮助。

Record.java ：

package co.uk.ing_simmons.aberdeensoundsites;

public class Record extends Activity implements OnClickListener {

static {
    System.loadLibrary("mp3lame");
}

private native void initEncoder(int numChannels, int sampleRate, int bitRate, int mode, int quality);

private native void destroyEncoder();

private native int encodeFile(String sourcePath, String targetPath);

[.....]
}

wrapper.c ：

void Java_co_uk_ing_simmons_aberdeensoundsites_Record_initEncoder(JNIEnv *env,
        jobject jobj, jint in_num_channels, jint in_samplerate, jint in_brate,
        jint in_mode, jint in_quality) {
[....]
