Can someone help me understand how to use OnPause() and OnResume() in this code? I'm trying to save last Selected or Captured image in imageView so when the user closes the program and comes back again he doesn't need to set or take the image again.
package com.example.thang.sdcardimagesactivity;

imageView.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
Switch();
return true;
}
});
}
public void Switch(){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), REQUEST_CODE);
}

if(bitmap != null && !bitmap.isRecycled())
{

//imageView.setBackgroundResource(0);

You can save an image to the SD card so it can be permanently accessed. It's best you do this immediately in the onActivityResult() method.
File imagesFolder = new File(Environment.getExternalStorageDirectory(), "ImagesFolder");
File file = new File(imagesFolder, "image.jpg");
String fileName = file.getAbsolutePath();
try {
FileOutputStream out = new FileOutputStream(file);
squareBitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
Log.e("Image", "Convert");
}
And to load it back when you restart the application (in onCreate or preferably in onResume):
try {
File imagesFolder = new File(Environment.getExternalStorageDirectory(), "ImagesFolder");
if (!imagesFolder.exists())
imagesFolder.mkdirs();
if (new File(imagesFolder, "image.jpg").exists()) {
String fileName = new File(imagesFolder, "image.jpg").getAbsolutePath();
Bitmap bitmap = BitmapFactory.decodeFile(fileName);
ImageView imageView = (ImageView) findViewById(R.id.image_view);
imageView.setImageBitmap(bitmap);
}
} catch (NullPointerException e) {
Log.e("Exception", "null");
}
Of course you can change the folder and image name.

Taking photo is OK but choose photo is wrong, when I click the button it shows album successfully, but when selecting a picture, it return whitout choosing that picture.
Use below code in onActivityResult();
Uri filePath = intent1.getData();
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), filePath );
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
picture.setImageBitmap(bitmap);
Paste below code after getting data from intent in onactivityresult.
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getActivity().getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
profilePic.setImageBitmap(BitmapFactory.decodeFile(picturePath));
I am a beginner of android development. I am trying to develop my own gallery. But I am facing a problem. When I go to SD card on my memory and choose a photo then I am trying to open image using my Image Viewer app. But when I select Image Viewer then another intent is called for choosing my image. But I directly want show the selected image on Imageview. Please anyone help me.

Let's assume you have an activity called ViewActivity that shows selected Image.
in your AndroidManifest.xml set your activity as a Image Viewer Activity by adding this :
<activity android:name=".ViewActivity">
<intent-filter>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="image/*"/>
</intent-filter>
</activity>
in onCreate() method of ViewActivity catch passed Image by doing this :
Intent intent = getIntent();
Uri data = intent.getData();
//Check If data type is Image
if (intent.getType().indexOf("image/") != -1)
{
myImageView.setImageURI(data);
}
try this Code replace whole class plz if success then i will explain to you
public class ImageGalleryDemoActivity extends Activity {
private static int RESULT_LOAD_IMAGE = 1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

I am new to android development, Now currently am working on an App for Image Steganography. So in my app , I need to convert an Image that i selected from gallery to Bits array(Each pixel will have a 8 bit value, thats what i mean), How can i do it ? Can anybody help me ?
public class ImageActivity extends Activity {
private Button btnSelectImage;
private Button btnEncode;
String Pathfile=new String();
public String selectedImagePath;
private ImageView myImage;
Bitmap result;
public static final int ICON_SELECT_GALLERY = 1;
private static final Object IMAGE_TAKER_REQUEST = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_image);
btnSelectImage = (Button) findViewById(R.id.button1);
btnEncode = (Button) findViewById(R.id.button2);
btnSelectImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
selectImage();
}
});
myImage = (ImageView) findViewById(R.id.imageView1);
}
public void selectImage() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, ICON_SELECT_GALLERY);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (resultCode == RESULT_OK)
{
if (requestCode == 1)
{
Uri selectedImageUri = data.getData();
String selectedImagePath = getPath(selectedImageUri);
Log.v("IMAGE PATH====>>>> ",selectedImagePath);
TextView imgPath=(TextView)findViewById(R.id.textView2);
imgPath.setText(selectedImagePath);
Pathfile=new String(selectedImagePath);
result = BitmapFactory.decodeFile(Pathfile);
myImage.setImageBitmap(result);
}
}
}
public String getPath(Uri uri)
{
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}
Pass Bitmap and method will return byte[]
public static byte[] getBytesFromBitmap(Bitmap bitmap){
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 70, stream);
return stream.toByteArray();
}
I'm trying to create an application that lets the user choose an image from the gallery or take a new one, and then send it via email. The function that takes the picture works perfectly (I can take it and then email it). But when I try to choose a picture, my application crashes. Here is my Java file:
public class Request extends Activity {
Button send;
Bitmap thumbnail;
File pic;
protected static final int CAMERA_PIC_REQUEST = 0;
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;

#Override

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
});

Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);

#Override

Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_EMAIL, new String[]{"test#test.com"});
i.putExtra(Intent.EXTRA_SUBJECT,"On The Job");
//Log.d("URI#!##!#!###!", Uri.fromFile(pic).toString() + " " + pic.exists());
i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(pic));
i.setType("image/png");
startActivity(Intent.createChooser(i,"Share you on the jobing"));
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
thumbnail = (Bitmap) data.getExtras().get("data");
ImageView image = (ImageView) findViewById(R.id.imageView1);
image.setImageBitmap(thumbnail);
try {
File root = Environment.getExternalStorageDirectory();
if (root.canWrite()){
pic = new File(root, "pic.png");
FileOutputStream out = new FileOutputStream(pic);
thumbnail.compress(CompressFormat.PNG, 100, out);
out.flush();
out.close();
}
} catch (IOException e) {
Log.e("BROKEN", "Could not write file " + e.getMessage());
}
}
if (requestCode == SELECT_PICTURE){
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
TextView uritv = null;
uritv.setText(selectedImagePath.toString());
}
}
public String getPath(Uri uri) {

Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}
I don't know what I need to change in my code, can anyone help me?
Seems clear to me
TextView uritv = null;
uritv.setText(selectedImagePath.toString());
In other words, you're trying to use a method on a null object.
My guess is you're not instancing the real TextView which would be something like
TextView uritv = (TextView) findViewById(R.id.uritv);
which, of course, depends on the real nomenclature of your textview

if u want to retrive direct from gallary then use this code
http://viralpatel.net/blogs/pick-image-from-galary-android-app/
this is my method for getting all file from sdcard and u just save this in one datacontroller class ohk dude
private void getallimages()
{
String[] STAR = { "*" };
final String[] columns = { MediaStore.Images.Thumbnails._ID , MediaStore.Images.Media.DATA};

int count = imagecursor.getCount();
for (int i = 0; i < count; i++) {
imagecursor.moveToPosition(i);
int id = imagecursor.getInt(image_column_index);
ImageItem imageItem = new ImageItem();
imageItem.id = id;
imageItem.filePath = imagecursor.getString(imagecursor.getColumnIndex(MediaStore.Images.Media.DATA));
lastId = id;
imageItem.img = MediaStore.Images.Thumbnails.getThumbnail(cntx.getContentResolver(), id,MediaStore.Images.Thumbnails.MICRO_KIND, null);
