I am working on an application in which I have a some text in English and Arabic. For the sake of example I can say it as a words meaning application. The word is in English and user will get it's meaning in Arabic.
For Example:
Test اختبار // Test is the word and then there is it's meaning in Arabic
But when I read this local file I don't get Arabic as intended. Instead I get some strange characters. I am making sure that file is UTF-8 encoded and when I read the file I again pass encoding scheme to be UTF-8..but it does not wwork. Code snippet is as follows:
InputStream inputStream = resources.openRawResource(R.raw.textfile);
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "utf-8"));
try {
String line;
while((line = reader.readLine()) != null) {
String[] strings = TextUtils.split(line, " ");
if (strings.length < 2) continue;
addWord(strings[0].trim(), strings[1].trim());
}
} finally {
reader.close();
}
Any help is appreciated..Thanks..!!!
I actually built an helper class that handles FileIO (and is completely compatible with Hebrew) so I guess Arabic will be no problem:

I am using the com.googlecode.mp4parser library to merge audio files. I have an external audio mp3 file which I store in raw resources. This file fails to merge due to following exception, Below is my code :
Reading a file from raw folder :
InputStream is = context.getResources().openRawResource(R.raw.my_mp3_file);
OutputStream output = null;
try {
File file = new File(context.getFilesDir(), "silence.mp3");
if(!file.exists()) {
file.createNewFile();
}
output = new FileOutputStream(file);
byte[] buffer = new byte[4 * 1024]; // or other buffer size
int read;
while ((read = is.read(buffer)) != -1) {
output.write(buffer, 0, read);
}
output.flush();
output.close();
fileReference= file;
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace(); // handle exception, define IOException and others
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Code that reads movie ( Which is failing ) :
if(fileReference.exists()) {
Movie m = new MovieCreator().build(fileReference.getAbsolutePath());
}
While getting this Movie m my code fails throwing the exception :
java.lang.NullPointerException: Attempt to invoke virtual method 'java.util.List com.coremedia.iso.boxes.MovieBox.getBoxes(java.lang.Class)' on a null object reference
It works for some mp3 files fails for raw resource files ? What's wrong here ?
Here are my conclusion and solution after a lot of research
MP4Parser for merging audio and video only use .m4a extension
String root = Environment.getExternalStorageDirectory().toString();
String audio = root + "/" + "tests.m4a";
String video = root + "/" + "output.mp4";
String output = root + "/" + "aud_vid.mp4";
mux(video, audio, output);
and here is the method
public boolean mux(String videoFile, String audioFile, String outputFile) {
Movie video;
try {
video = new MovieCreator().build(videoFile);
} catch (RuntimeException e) {
e.printStackTrace();
return false;
} catch (IOException e) {
e.printStackTrace();
return false;
}
Movie audio;
try {
audio = new MovieCreator().build(audioFile);
} catch (IOException e) {
e.printStackTrace();
return false;
} catch (NullPointerException e) {
e.printStackTrace();
return false;
}
Track audioTrack = audio.getTracks().get(0);
video.addTrack(audioTrack);
Container out = new DefaultMp4Builder().build(video);
FileOutputStream fos;
try {
fos = new FileOutputStream(outputFile);
} catch (FileNotFoundException e) {
e.printStackTrace();
return false;
}
BufferedWritableFileByteChannel byteBufferByteChannel = new BufferedWritableFileByteChannel(fos);
try {
out.writeContainer(byteBufferByteChannel);
byteBufferByteChannel.close();
fos.close();
} catch (IOException e) {
e.printStackTrace();
return false;
}
return true;
}
private static class BufferedWritableFileByteChannel implements WritableByteChannel {
private static final int BUFFER_CAPACITY = 1000000;
private boolean isOpen = true;

private BufferedWritableFileByteChannel(OutputStream outputStream) {
this.outputStream = outputStream;

}

}
}
Seem like this issue happens because Google devs have forgotten to handle that NullPointerException case. After several hours diving into the code base, I finally found the solution and It works very fine, you can try this:
Movie movie;
try{
movie = MovieCreator.build(videoPath);
}catch(NullPointerException e){
Log.d("AsyncTask", "Catch null getMovieBoxes");
FileDataSourceImpl fileDataSource = new FileDataSourceImpl(new File(videoPath));
IsoFile isoFile = new IsoFile(fileDataSource);
List<TrackBox> trackBoxes = isoFile.getBoxes(TrackBox.class);
for (TrackBox trackBox : trackBoxes) {
SchemeTypeBox schm = Path.getPath(trackBox, "mdia[0]/minf[0]/stbl[0]/stsd[0]/enc.[0]/sinf[0]/schm[0]");
if (schm != null && (schm.getSchemeType().equals("cenc") || schm.getSchemeType().equals("cbc1"))) {
movie.addTrack(new CencMp4TrackImplImpl(fileDataSource.toString() + "[" + trackBox.getTrackHeaderBox().getTrackId() + "]", trackBox));
} else {
movie.addTrack(new Mp4TrackImpl(fileDataSource.toString() + "[" + trackBox.getTrackHeaderBox().getTrackId() + "]" , trackBox));
}
}
}
I've created Test.txt on sdcard and write string "test example" on it.
after that, I replace string "test" by "etc" in Test.txt.
this is my code :
String origin_str, old_str , new_str;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_t2);
origin_str = "test example";
old_str = "test";
new_str = "etc";
Button bt_create2 = (Button)findViewById(R.id.bt_createfileT2);
bt_create2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
File newFolder = new File(Environment.getExternalStorageDirectory(), "TestFolder");
if (!newFolder.exists()) {
newFolder.mkdir();
}
File file = new File(newFolder, "Test" + ".txt");
if (!file.exists()) {
file.createNewFile();
FileOutputStream fOut = new FileOutputStream(file);
OutputStreamWriter myOutWriter =new OutputStreamWriter(fOut);
myOutWriter.append(origin_str);
myOutWriter.close();
fOut.close();
}
} catch (Exception e) {
System.out.println("e: " + e);
}
}
});
Button bt_replacefileT2 = (Button)findViewById(R.id.bt_replacefileT2);
bt_replacefileT2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
File file = new File(Environment.getExternalStorageDirectory() + "/TestFolder/Test.txt");
FileInputStream in = new FileInputStream(file);
int len = 0;
byte[] data1 = new byte[1024];
while ( -1 != (len = in.read(data1)) ){
if(new String(data1, 0, len).contains(old_str)){
String s = "";
s = s.replace(old_str, new_str);
}
}
}
catch (Exception e){
e.printStackTrace();
}
}
});
with this code, it was create Test.txt on sdcard and write "test example" on it.
but when replace string "test" by "etc", it not working.
how to fix it?
I will give my code, always worked for me :)
Hope thi can help you :DD

Here how I write bytes to a file. I'm using FileOutputStream
private final Handler handler = new Handler(){
#Override
public void handleMessage(Message msg) {
FragmentActivity activity = getActivity();
byte[] readBuffer = (byte[]) msg.obj;
FileOutputStream out = null;
try {
out = new FileOutputStream("myFile.xml");
out.write(readBuffer);
out.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
and now I want to open that file, so I need to have path of that file. So how I need to open that file?
EDIT:
Here how I read from file, but I can't see anything...
BufferedReader reader = null;
FileInputStream s = null;
try {
s = new FileInputStream("mano.xml");
reader = new BufferedReader(new InputStreamReader(s));
String line = reader.readLine();
Log.d(getTag(), line);
while (line != null) {
Log.d(getTag(), line);
line = reader.readLine();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
I recommend to use this for writting:
OutputStream out = new FileOutputStream(Environment.getExternalStorageDirectory().getAbsolutePath()+"/yourfilename");
So to read the location:
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/"+transaction.getUniqueId()+".pdf");
To read the path:
file.getAbsolutePath();
Your file is save in path /Data/Data/Your package Name/files/myFile.xml
you can use this.getFileDir() method to get the path of the files folder on the Application.
So use this.getFileDir() + "myFile.xml" to read the file.
How it is reported inside the developers guide you have to specify where you want to save your file. You can choose between:
Saving the file in the internal storage:
String filename = "myfile";
String string = "Hello world!";
FileOutputStream outputStream;
try {
outputStream = openFileOutput(filename, Context.MODE_PRIVATE);
outputStream.write(string.getBytes());
outputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
Or on second instance you could save your file in external storage:
// Checks if external storage is available to at least read
public boolean isExternalStorageReadable() {
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state) || Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
return true;
}
return false;
}
Just remember to set permissions!!!!

Is there any way to install a vCard using android app, as soon as it starts for the first time.
Although for running any block of code for the first time, I can use these lines ...
if (isFirstTime()) {
//First time code
}
and
private boolean isFirstTime()
{
SharedPreferences preferences = getPreferences(MODE_PRIVATE);
boolean ranBefore = preferences.getBoolean("RanBefore", false);
if (!ranBefore) {
SharedPreferences.Editor editor = preferences.edit();
editor.putBoolean("RanBefore", true);
editor.commit();
}
return ranBefore;
}
but how will I be able to install a vCard from app.
Note: Although I have the vCard already made, and can be put in the raw directory.
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(storage_path+vfile)),"text/x-vcard");
startActivity(intent);
Edit
Copy vcard to sdcard
private void copyAssets() { AssetManager assetManager = getAssets();
String[] files = null;
try { files = assetManager.list(""); } catch (IOException e)
{ Log.e("tag", "Failed to get asset file list.", e);
} for(String filename : files)
{
InputStream in = null; OutputStream out = null;
try { in = assetManager.open(filename);
File outFile = new File(getExternalFilesDir(null), filename);
out = new FileOutputStream(outFile); copyFile(in, out); } catch(IOException e) {
Log.e("tag", "Failed to copy asset file: " + filename, e); }
finally {
if (in != null) { try { in.close();
} catch (IOException e) { // NOOP }
} if (out != null) {
try { out.close(); } catch (IOException e) { // NOOP }
}
}

} private void copyFile(InputStream in, OutputStream out) throws IOException {
byte[] buffer = new byte[1024]; int read; while((read = in.read(buffer)) != -1){ out.write(buffer, 0, read);
} }
Then type the location where I have written storage_path
