正如这个问题的标题所说，我的代码如下：
protected void PayMessageBox(final String Type) {
AlertDialog alertbox = new AlertDialog.Builder(context)
.setMessage("are you sure?")
.setPositiveButton("yes",
new DialogInterface.OnClickListener() {
// do something when the button is clicked
public void onClick(DialogInterface arg0, int arg1) {
new AsyncGetAccountInfo().execute(Type);
}
})
.setNegativeButton("no",
new DialogInterface.OnClickListener() {
// do something when the button is clicked
public void onClick(DialogInterface arg0, int arg1) {
}
}).show();
}
在AsyncGetAccountInfo（）中，我有以下代码：
protected class AsyncGetAccountInfo extends AsyncTask<String, Void, String> {
// private Boolean Havemoney = true;
@Override
protected String doInBackground(String... params) {
try {
String allPlace = null;
RestAPI api = new RestAPI();
try {
SharedPreferences sharedPreferences = getSharedPreferences(
"MyData", context.MODE_PRIVATE);
String E_MSISDN = sharedPreferences.getString("MSISDN",
"N/A");
EncryptDecryptWithDESUsingPassPhrase security = new EncryptDecryptWithDESUsingPassPhrase();
// E_MSISDN=security.encrypt(E_MSISDN);
String E_ACTIVATIONCODE = sharedPreferences.getString(
"ACTIVATIONCODE", "N/A");
Long ReqId = sharedPreferences.getLong("REQID", -1);
String Key = ReqId + E_ACTIVATIONCODE;
security.setKey(Key);
String E_IMEI = security.encrypt(IMEI);
String E_TYPE = security.encrypt(params[0]);
JSONObject jsonObj = api.ReduceCharge(E_IMEI,E_MSISDN,
E_TYPE);
JSONParser parser = new JSONParser();
allPlace = parser.parseReduceCharge(jsonObj);
} catch (Exception e) {
// TODO Auto-generated catch block
// Log.d("AsyncUserDetails", e.getMessage());
return null;
}
return allPlace;
} catch (Exception e) {
// TODO Auto-generated catch block
// Log.d("AsyncUserDetails", e.getMessage());
return null;
}
// return Havemoney;
}
@Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
if (result != null) {
SharedPreferences sharedPreferences = getSharedPreferences(
"MyData", context.MODE_PRIVATE);
Long ReqId = sharedPreferences.getLong("REQID", -1);
EncryptDecryptWithDESUsingPassPhrase security = new EncryptDecryptWithDESUsingPassPhrase();
String E_ACTIVATIONCODE = sharedPreferences.getString(
"ACTIVATIONCODE", "N/A");
ReqId = sharedPreferences.getLong("REQID", -1);
String Key = ReqId + E_ACTIVATIONCODE;
security.setKey(Key);
if (security.decrypt(result).equals("1")) {
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putLong("REQID", ++ReqId);
editor.commit();
// new AsyncSaveMobileAndActivationCode().execute(result);
dialog.dismiss();
new AsyncPersonIsPaid().execute();
if(true)
{
//new AsyncUserPackagepaid().execute();
}
if (SingleVideos.size() > 0) {
// progressBar.startAnimation(set);
DownloadVideo(SingleVideos.get(0).VIDEOURL);
}
} else if (security.decrypt(result).equals("-2")) {
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putLong("REQID", ++ReqId);
editor.commit();
Toast.makeText(context,
"low balance",
Toast.LENGTH_LONG).show();
} else {
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putLong("REQID", ++ReqId);
editor.commit();
Toast.makeText(
context,
"try again",
Toast.LENGTH_LONG).show();
}
} else {
Toast.makeText(
context,
"db down, try later",
Toast.LENGTH_LONG).show();
// LL_Register_Button.setClickable(true);
}
}
}
代码到达以下点后：
if (SingleVideos.size() > 0) {
// progressBar.startAnimation(set);
DownloadVideo(SingleVideos.get(0).VIDEOURL);
}
调用DownloadVideo，其代码如下：
private void DownloadVideo(final String VIDEO_URL) {
try {
if (VIDEO_URL != null && VIDEO_URL.length() > 0) {
File file = new File(Environment
.getExternalStoragePublicDirectory(
Environment.DIRECTORY_MOVIES).getAbsolutePath());
VideoPath = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_MOVIES).getAbsolutePath()
+ "/" + Uri.parse(VIDEO_URL).getLastPathSegment();
getfile(file);
int countVideo = 0;
for (File video_name : fileList) {
if (video_name.getName().equals(
Uri.parse(VIDEO_URL).getLastPathSegment()))
countVideo++;
}
if (countVideo > 0) {
PersonInfo.mMediaPlayer.pause();
Intent intent = new Intent(
android.content.Intent.ACTION_VIEW);
Uri myUri = Uri.parse(VideoPath);
String VideoExtention = VideoPath.substring(0,
VideoPath.lastIndexOf('.'));
String extentions = "video/"
+ VideoPath.substring(VideoExtention.length() + 1);
intent.setDataAndType(myUri, extentions);
startActivity(intent);
} else {
if (IsOnline) {// stream video
Intent intent = new Intent(context,
PlayVideoActivity.class);
intent.putExtra("VIDEOPATH", VIDEO_URL);
intent.putExtra("ISONLINE", true);
startActivity(intent);
}
if (IsOnline == false) {// donwload video
float VideoSize = 0f;
String last2 = (TV_VideoSize.getText() == null
|| TV_VideoSize.length() < 2 ? "0"
: ((String) TV_VideoSize.getText())
.substring(TV_VideoSize.getText()
.length() - 2));
last2 = last2.trim();
String NewString = ((String) TV_VideoSize.getText())
.replaceAll(last2, "");
if (last2.equals("KB")) {
VideoSize = Float.valueOf(NewString) * 1024f;
} else if (last2.equals("MB")) {
VideoSize = Float.valueOf(NewString) * 1024f * 1024f;
} else if (last2.equals("GB")) {
VideoSize = Float.valueOf(NewString) * 1024f * 1024f * 1024f;
} else {
VideoSize = Float.valueOf(NewString);// byte
}
StatFs stat = new StatFs(Environment
.getExternalStoragePublicDirectory(
Environment.DIRECTORY_MOVIES)
.getAbsolutePath());
float bytesAvailable = (float) stat.getBlockSize()
* (float) stat.getAvailableBlocks();
if (bytesAvailable > VideoSize) {
myTask = new MyTask();
myTask.execute(VIDEO_URL);
// myTask.cancel(true);
} else {
}
}
}
}
} catch (Exception e) {
// TODO Auto-generated catch block
Toast.makeText(context, "Connection Error", Toast.LENGTH_SHORT)
.show();
e.printStackTrace();
}
}
代码进入上述代码的这一部分：
if (IsOnline) {// stream video
Intent intent = new Intent(context,
PlayVideoActivity.class);
intent.putExtra("VIDEOPATH", VIDEO_URL);
intent.putExtra("ISONLINE", true);
startActivity(intent);
}
问题在于上面代码中的startActivity（intent），它基本上是VideoView的活动，甚至是它的onCreate被调用，当它想要执行videoView.start（）方法时，它会崩溃。
出了什么问题？
