我的应用程序在 Sony Experia (2.3) 上成功运行,但在三星 Galaxy Tab (4.1) 上运行时出现异常。我的问题是,在录制视频并将其转换为 base64 字符串后,在将其解析为肥皂时出现错误。
这是我捕获视频的代码(传递意图):
Intent videoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
videoIntent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 10);
videoIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);
startActivityForResult(videoIntent, ACTION_TAKE_VIDEO);
关于活动结果方法:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if ((requestCode == ACTION_TAKE_VIDEO && resultCode == RESULT_OK)) {
System.out.println("capturing video");
Uri selectedImage = data.getData();
String videoPath = getRealPathFromURI(selectedImage);
Bitmap bm = ThumbnailUtils.createVideoThumbnail(videoPath, MediaStore.Images.Thumbnails.MINI_KIND);
videoview.setImageBitmap(bm);
System.out.println("videobitmap=="+bm);
bytes[]datas = null;
String dataPath = videoPath;
InputStream is = null;
try {
is = new FileInputStream(dataPath);
datas = readBytes(is);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
String encodedImage = Base64.encodeToString(datas, Base64.DEFAULT);
isInternetPresent = cd.isConnectingToInternet();
if (isInternetPresent) {
new BufferingVideo().execute(encodedImage);
} else {
Toast.makeText(getApplicationContext(), "Sorry, we couldn't connect to server, please check your
internet connection", Toast.LENGTH_LONG).show();
}
}
}
public byte[] readBytes(InputStream inputStream) throws IOException {
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
int len = 0;
while ((len = inputStream.read(buffer)) != -1) {
byteBuffer.write(buffer, 0, len);
}
return byteBuffer.toByteArray();
}
public String getRealPathFromURI(Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
现在将 base64 字符串传递给 Webservice:
protected String doInBackground(String... params) {
String st = params[0];
System.out.println("st==== " + st);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME4);
System.err.println("Request = " + request);
request.addProperty("VideoBuffer", st);
request.addProperty("VideoName", "VideoCar");
request.addProperty("ModuleName", modulename);
}
我的 Logcat 错误是:
致命异常:AsyncTask #5 java.lang.RuntimeException:执行 doInBackground() 时发生错误 在 android.os.AsyncTask$3.done(AsyncTask.java:299) 在 java.util.concurrent.FutureTask$Sync.innerSetException(FutureTask.java:273) 在 java.util.concurrent.FutureTask.setException(FutureTask.java:124) 在 java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:307) 在 java.util.concurrent.FutureTask.run(FutureTask.java:137) 在 java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1076) 在 java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:569) 在 java.lang.Thread.run(Thread.java:856) 引起:java.lang.OutOfMemoryError 在 java.lang.AbstractStringBuilder.enlargeBuffer(AbstractStringBuilder.java:94) 在 java.lang.AbstractStringBuilder.append0(AbstractStringBuilder.java:145) 在 java.lang.StringBuffer.append(StringBuffer.java:219) 在 org.ksoap2.serialization.SoapObject.toString(SoapObject.java:456) 在 java.lang.StringBuilder.append(StringBuilder.java:202) 在 web.org.HouseRentInsertAds$BufferingVideo.doInBackground(HouseRentInsertAds.java:897) 在 web.org.HouseRentInsertAds$BufferingVideo.doInBackground(HouseRentInsertAds.java:1) 在 android.os.AsyncTask$2.call(AsyncTask.java:287) 在 java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:305)
请给我一个解决方案。
