I'm not sure what is going on. I click the button to take the image and my app closes.
I'm attempting to make an app to capture and use an image. I haven't even been able to capture the image.

Any Kind of help is appreciated as I am a newbie
With android sdk >= 23, some permissions e.g. WRITE_EXTERNAL_STORE, READ_EXTERNAL_STORE, etc. you must request it in java code.
Therefore, when user starts using feature need permission, android will show a dialog and user can grant or cancel a permission. You can read more about it on developer.android.com.

Make com/android/internal/telephony folder structure inside src folder and put ITelephony.aidl file inside the telephony folder.
i am creating an application which i want share images to any social platform.
i used a grid view successfully, which shows all the images and can be viewed in specific full image activity to show the user selected image.
i want to add a social share function to the applications which get the image location and share to the social platform.
Here is my MainActivity.java
package com.jai.desimeme;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.GridView;
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GridView gridView = (GridView) findViewById(R.id.grid_view);
// Instance of ImageAdapter Class
gridView.setAdapter(new ImageAdapter(this));
gridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
// Sending image id to FullScreenActivity
Intent i = new Intent(getApplicationContext(), FullImageActivity.class);
// passing array index
i.putExtra("id", position);
startActivity(i);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
with my activity_main.XML
<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"

android:gravity="center"
android:horizontalSpacing="5dp"
android:numColumns="4"
android:stretchMode="columnWidth"
android:verticalSpacing="5dp" >
</GridView>
i used the FullImageActivity.java for the preview of image selected //here i want to add the sharing link.
package com.jai.desimeme;

imageView.setImageResource(imageAdapter.mThumbIds[position]);
}
#Override

File sd = Environment.getExternalStorageDirectory();
String fileName = "test.png";
File dest = new File(sd, fileName);
try {
FileOutputStream out;
out = new FileOutputStream(dest);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
} catch (FileNotFoundException e) {

switch (item.getItemId()) {

shareIntent.setType("image/jpeg");
startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.share)));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
for above code i used this full_image.xml activity.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

android:layout_width="100dp" android:layout_height="100dp"
android:src="#drawable/image_border"
style="#style/myImageView" />
</LinearLayout>
in here i created ImageAdapter.java to store the image files.
package com.jai.desimeme;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;

private Context mContext;
// Keep all Images in array
public Integer[] mThumbIds = {

};
// Constructor
public ImageAdapter(Context c){
mContext = c;
}
#Override
public int getCount() {
return mThumbIds.length;
}
#Override
public Object getItem(int position) {
return mThumbIds[position];
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView = new ImageView(mContext);
imageView.setImageResource(mThumbIds[position]);
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setLayoutParams(new GridView.LayoutParams(70, 70));
return imageView;
}

guide me how to add sharing link to this application, i tried so many ways but end up in errors.
You can use this on any click event of your UI element.
BitmapDrawable bm = (BitmapDrawable) yourImageView.getDrawable();
Bitmap mysharebmp = bm.getBitmap();
String path = Images.Media.insertImage(getContentResolver(),
mysharebmp, "MyImage", null);

I have an app with 2 classes, I need my app to open the second class CardActivity when the NFC tag tapped/swiped. The app opens fine, but MainActivity is run, instead of CardActivity.
I would hazard a guess that this is an issue with my manifest, but it looks correct. Here it is regardless:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.spotsofmagic.spotsofmagic"
android:versionCode="1"

<uses-permission android:name="android.permission.NFC" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

<application

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity

android:label="#string/app_name" >
<!-- Handle a collectable card NDEF record -->
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<data android:mimeType="application/vnd.spotsofmagic.spotsofmagic"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
</application>
</manifest>
I'm confident the tag itself is correct, as I have opened it in another app to view it's contents.
Below are the two classes.
CardActivity:
package com.spotsofmagic.spotsofmagic;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.content.Intent;
import android.nfc.NdefMessage;
import android.nfc.NdefRecord;
import android.nfc.NfcAdapter;
import android.os.Bundle;
import android.os.Parcelable;
import android.util.Log;
import android.bluetooth.*;
public class CardActivity extends Activity implements OnClickListener {
private static final String TAG = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.card_activity);
// see if app was started from a tag and show game console
Intent intent = getIntent();
Log.e(TAG, "Hello world. Intent Type: "+ intent.getType());
if(intent.getType() != null && intent.getType().equals(MimeType.NFC_DEMO)) {
Parcelable[] rawMsgs = getIntent().getParcelableArrayExtra(NfcAdapter.EXTRA_NDEF_MESSAGES);
NdefMessage msg = (NdefMessage) rawMsgs[0];
NdefRecord cardRecord = msg.getRecords()[0];
String payload = new String(cardRecord.getPayload());
turnBluetoothOn(payload);
}
}
private void turnBluetoothOn(String payload) {
final AlertDialog.Builder builder=new AlertDialog.Builder(this);
builder.setTitle("Alert Dialog");
builder.setMessage(payload);
builder.setIcon(android.R.drawable.ic_dialog_alert);
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter == null) {
// Device does not support Bluetooth
}
if (!mBluetoothAdapter.isEnabled()) {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, 1);
}
android.os.Process.killProcess(android.os.Process.myPid());
}
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
}
MainActivity:
package com.spotsofmagic.spotsofmagic;
import android.app.Activity;
import android.app.AlertDialog;
import android.bluetooth.BluetoothAdapter;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.content.Intent;
import android.nfc.NdefMessage;
import android.nfc.NdefRecord;
import android.nfc.NfcAdapter;
import android.os.Bundle;
import android.os.Parcelable;
import android.util.Log;
import android.widget.TextView;
public class MainActivity extends Activity implements OnClickListener {
private static final String TAG = "Activity...";
private NfcAdapter mAdapter;
private TextView mTextView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
// grab our NFC Adapter
mAdapter = NfcAdapter.getDefaultAdapter(this);
// TextView that we'll use to output messages to screen
mTextView = (TextView)findViewById(R.id.text_view);
displayMessage("Loading payload...");
}
private void displayMessage(String message) {
mTextView.setText(message);
}
public void onClick(DialogInterface arg0, int arg1) {
// TODO Auto-generated method stub
}
}
Here is the code I used to write the tag. This is done on a different app incidentally:
NdefRecord appRecord = NdefRecord.createApplicationRecord("com.spotsofmagic.spotsofmagic");
// record that contains our custom "retro console" game data, using custom MIME_TYPE
byte[] payload = getPayload().getBytes();
byte[] mimeBytes = MimeType.NFC_DEMO.getBytes(Charset.forName("US-ASCII"));
NdefRecord cardRecord = new NdefRecord(NdefRecord.TNF_MIME_MEDIA, mimeBytes,
new byte[0], payload);
NdefMessage message = new NdefMessage(new NdefRecord[] { cardRecord, appRecord});
// Some code here removed for readability
Ndef ndef = Ndef.get(tag);
if (ndef != null) {
ndef.connect();
ndef.writeNdefMessage(message);
Does the NDEF message on the tag contain an Android Application Record? That could explain how MainActivity is launched. However, that can only be the cause if the AAR is the first record of the NDEF message on the tag or if the first record does not match the intent filter.
