我想將圖像和歌曲等文件上傳到我的PHP服務器，但是當我嘗試上傳大文件（文件大小5MB或更大）時，我正面臨一些錯誤。我能夠成功上傳500kb附近的文件。請幫我讓我知道，我怎麼能上傳大文件的大小。對於Java文件如何在Android中將大文件上傳到PHP服務器
代碼：
public class UploadAudioDemo extends Activity {
private static final int SELECT_IMAGE = 1, SELECT_AUDIO = 2;
String selectedPath = "";
Button ImageBtn, AudioBtn;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageBtn = (Button)findViewById(R.id.image_btn);
AudioBtn = (Button)findViewById(R.id.audio_btn);
ImageBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Image"), SELECT_IMAGE);
}
});
AudioBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setType("audio/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Audio"), SELECT_AUDIO);
}
});

我也包括以下Uses Permissions:

我已經等了25-30分鐘，但屏幕保持不變，也沒有該文件被上傳到服務器...
請幫助..
上SO將提供一些類似的問題。搜索。如[鏈接1]（http://stackoverflow.com/questions/10276647/uploading-video-upto-50mb-to-the-server），[鏈接2]（http://stackoverflow.com/questions/10838653/android-large-video-uploadloading-to-server），[Link 3]（http://stackoverflow.com/questions/5089891/android-video-upload-to-php-server）。前兩個鏈接可能有幫助。 –
@SiddharthLele Link1和Link2都是非常棒的教程，但它們不能解決我的問題。我已經嘗試根據教程修改代碼，但在執行上傳到服務器的文件的大小後是0B。所以請看看我的代碼，並幫助我..謝謝.. –
我只是指着你在正確的方向。我在這方面沒有經驗。 –
