Step 1: Get the path to the store. We use the
/sdcard/Android/data/
The path of the package name/is convenient for us to test and view
String path=MyApplication.getContextObject().getExternalFilesDir("").toString();
File file=new File(path);
Step 2: Create a new empty file on the file system based on the path information stored in the file
File finalImageFile = new File(file, System.currentTimeMillis() + ".jpg");
try {
finalImageFile.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
Step 3: Put bytes into the file output stream
FileOutputStream fos = null;
try {
fos = new FileOutputStream(finalImageFile);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Step 4: Compress the picture into picture format
BitmapDrawable bitmapDrawable = (BitmapDrawable)MyApplication.getContextObject().getResources().getDrawable(R.drawable.account);
Bitmap bitmap=bitmapDrawable.getBitmap();
if (bitmap == null) {
Toast.makeText(MyApplication.getContextObject(), " Picture does not exist ",Toast.LENGTH_LONG).show();
return;
}
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
try {
fos.flush();
fos.close();
Toast.makeText(MyApplication.getContextObject(), " The picture is saved in: "+ finalImageFile.getAbsolutePath(), Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}
Complete code
String path=MyApplication.getContextObject().getExternalFilesDir("").toString();
File file=new File(path);
File finalImageFile = new File(file, System.currentTimeMillis() + ".jpg");
try {
finalImageFile.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
FileOutputStream fos = null;
try {
fos = new FileOutputStream(finalImageFile);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
BitmapDrawable bitmapDrawable = (BitmapDrawable)MyApplication.getContextObject().getResources().getDrawable(R.drawable.account);
Bitmap bitmap=bitmapDrawable.getBitmap();
if (bitmap == null) {
Toast.makeText(MyApplication.getContextObject(), " Picture does not exist ",Toast.LENGTH_LONG).show();
return;
}
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
try {
fos.flush();
fos.close();
Toast.makeText(MyApplication.getContextObject(), " The picture is saved in: "+ finalImageFile.getAbsolutePath(), Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}
