Android日志不打印
Android日志不打印
提问于 2016-10-25 17:10:43
我正在使用TarsosDsp，我不知道我的问题是否与库有关。如果有人能帮我解决这个问题，我会很高兴的。这是我的密码：
public class MainActivity extends AppCompatActivity {
private static final String TAG = "MyActivity";
private Handler handler;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
handler = new Handler();
}
protected void run(View view) {
new AndroidFFMPEGLocator(this);
new Thread(new Runnable() {
@Override
public void run() {
handler.post(new Runnable() {
@Override
public void run() {
File externalStorage = Environment.getExternalStorageDirectory();
File sourceFile = new File(externalStorage.getAbsolutePath(), "/440.wav");
final int bufferSize = 4096;
final int fftSize = bufferSize / 2;
final int sampleRate = 44100;
AudioDispatcher audioDispatcher;
audioDispatcher = AudioDispatcherFactory.fromPipe(sourceFile.getAbsolutePath(), sampleRate, bufferSize, 0);
audioDispatcher.addAudioProcessor(new AudioProcessor() {
FFT fft = new FFT(bufferSize);
final float[] amplitudes = new float[fftSize];
@Override
public boolean process(AudioEvent audioEvent) {
float[] audioBuffer = audioEvent.getFloatBuffer();
fft.forwardTransform(audioBuffer);
fft.modulus(audioBuffer, amplitudes);
for (int i = 0; i < amplitudes.length; i++) {
Log.println(Log.DEBUG, TAG, String.format("Amplitude at %3d Hz: %8.3f", (int) fft.binToHz(i, sampleRate), amplitudes[i]));
}
return true;
}
@Override
public void processingFinished() {
Toast.makeText(getApplicationContext(), "salam", Toast.LENGTH_SHORT).show();
}
});
audioDispatcher.run();
}
});
}
}).start();
}}
问题是日志线在
Log.println(Log.DEBUG, TAG, String.format("Amplitude at %3d Hz: %8.3f", (int) fft.binToHz(i, sampleRate), amplitudes[i]));不会打印任何东西。有什么帮助吗？这是我的日志：

实际上，android (java)在登录主线程以外的线程时以一种奇怪的方式工作。

关闭Android的即时运行功能，卸载应用程序，清理项目，然后运行应用程序。这帮了我一次，也许是给你的。祝你好运。

你可能忘记打电话给protected void run(View view)方法了吗？
