as well my java code is like below

public File addToDiskCache(String imageName, Bitmap inImage) {

    Log.e("Add to Disk",imageName);

    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);

    if(!mCacheDir.exists()){
        mCacheDir.mkdirs();
    }

    File filePath=new File(mCacheDir.getPath()+File.separator+imageName);
    if(!filePath.exists()) {
        try {
            filePath.createNewFile();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    OutputStream os=null;
    try {
           os= new FileOutputStream(filePath.getPath());
            os.write(bytes.toByteArray());
            os.flush();
        } catch (IOException e) {
            Log.e("Write err",filePath.toString());
        }finally {
        try {
            os.close();
        } catch (IOException e) {
            e.printStackTrace();

maybe your bitmap is too large or maybe it is not caused by this method, check your other codes to see if you have forgot to recycle object, especially bitmap. — Harlan

compress is ineffective

try this when you use bitmap from file

 private Bitmap sampleImage(Bitmap bitmap, int reqWidth, int reqHight) {


        //first decode
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile("FILE_PATH",options);
        //seconde deconde
        options.inSampleSize = caculateSampleSize(options,reqWidth,reqHight);
        options.inJustDecodeBounds = false;


        bitmap = BitmapFactory.decodeFile("FILE_PATH",options);
         return bitmap;

    }

private int caculateSampleSize(BitmapFactory.Options options, int reqWidth, int reqHight) {
    int screenWidth;
    int screenHight;
    screenWidth = (reqWidth == 0 ? this.getResources().getDisplayMetrics().widthPixels : reqWidth);
    screenHight = (reqHight == 0 ? this.getResources().getDisplayMetrics().heightPixels : reqHight);
    int sampleWith = options.outWidth / screenWidth;
    int sampleHight = options.outHeight / screenHight;
    //use max
    return  sampleWith > sampleHight ? sampleWith : sampleHight;
}
