結果を返すときにビットマップ画像があり、それを SD カードの Photo Art Camera フォルダーに保存したいのですが、保存されません。「写真が正常に保存されませんでした」というトーストが表示されます。

これはコードです：

mSave.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View arg0) {
        File cacheDir;
        Bitmap bitmap = result;

        // String path = Environment.getExternalStorageDirectory().toString();
        OutputStream fOut = null;
        Date d = new Date();

        if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED)) {
            cacheDir = new File(android.os.Environment.getExternalStorageDirectory(), "Photo Art Camera");
        } else { cacheDir = MainActivity.this.getCacheDir(); }

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

        File file = new File(cacheDir, "PhotoMarge" + d.getTime() + ".jpg");
        try {
            fOut = new FileOutputStream(file);
            bitmap.compress(CompressFormat.PNG, 150, fOut);
            // getImageBitmap(myurl).compress(Bitmap.CompressFormat.JPEG, 85, fOut);
            fOut.flush();
            fOut.close();

            Toast.makeText(MainActivity.this, "Photo Saved Sucessfully", 500).show();

            // mDialog.dismiss();
            // MediaStore.Images.Media.insertImage(getContentResolver(),file.getAbsolutePath(),file.getName(),file.getName());
        }
        catch (FileNotFoundException e) { e.printStackTrace(); }
        catch (Exception e) {
            e.printStackTrace();
            Toast.makeText(MainActivity.this, "Photo Not Saved Sucessfully", 500).show();
        }
    }
});

i removed my misstake from code .Actually i am saving another bitmap instead saving and converting framelayout bitmap
File cacheDir;
                        frame.setDrawingCacheEnabled(true);

                        icon = Bitmap.createBitmap(frame.getDrawingCache());

                        Bitmap bitmap = icon;

                    //  String path = Environment.getExternalStorageDirectory().toString();
                        OutputStream fOut = null;
                        Date d=new Date();

                        if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
                            cacheDir=new File(android.os.Environment.getExternalStorageDirectory(),"Photo Art Camera");
                        else
                            cacheDir=MainActivity.this.getCacheDir();
                        if(!cacheDir.exists())
                            cacheDir.mkdirs();

                        File file = new File(cacheDir, "PhotoMarge"+d.getTime()+".jpg");
                        try {
                            fOut = new FileOutputStream(file);
                            bitmap.compress(CompressFormat.PNG, 100, fOut);
                            //getImageBitmap(myurl).compress(Bitmap.CompressFormat.JPEG, 85, fOut);
                            fOut.flush();
                            fOut.close();
                            count();
                            Toast.makeText(MainActivity.this, "Photo Saved Sucessfully", 500).show();

                        //  mDialog.dismiss();

                            //MediaStore.Images.Media.insertImage(getContentResolver(),file.getAbsolutePath(),file.getName(),file.getName());
                        } catch (FileNotFoundException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        } catch (Exception e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                            Toast.makeText(MainActivity.this, "Photo Not Saved Sucessfully", 500).show();

                        }

異なる引数で圧縮している場合は、100 または 120 にする必要があります。

OutputStream fOut = new FileOutputStream(output);
merged.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
fOut.flush();
fOut.close();

Toast.makeText(getApplicationContext(), "Saved", Toast.LENGTH_SHORT).show();

また

  String strMyImagePath = f.getAbsolutePath();
             FileOutputStream fos = null;
             try {
                 fos = new FileOutputStream(f);
                 bitmap.compress(Bitmap.CompressFormat.PNG,70, fos);

                 fos.flush();
                 fos.close();
              //   MediaStore.Images.Media.insertImage(getContentResolver(), b, "Screen", "screen");
             }catch (FileNotFoundException e) {

                 e.printStackTrace();
             } catch (Exception e) {

                 e.printStackTrace();
             }
