Fail to load image from Uri in third activity

Fail to load image from Uri in third activity - java

I'm beginner in Android Studio. My app allows me to add users(fn,ln,adrs,Uri::ImageUri) and list them and view their info.
I want to be able to display one user's info when clicking on my listview.
The problem is that i only get a blank space instead of my desired imageview.
My main activity :
public class MainActivity extends AppCompatActivity {
public static ArrayList <User> users =new ArrayList <User>();
public static User userSelected;
public static ListView mListView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(activity_main);
mListView = (ListView) findViewById(R.id.List);
}
public void InputInfo(View view) {
Intent AddEmployee = new Intent(this, NewEmployeeInfo.class);
startActivityForResult(AddEmployee,0);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(0, resultCode, data);
finaltest =NewEmployeeInfo .targetUri ;
UserAdapter useradapter;
useradapter = new UserAdapter (MainActivity .this, android.R.layout.simple_list_item_1, users ) ;
mListView.setAdapter(useradapter );
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> adapter, View view, int position, long arg) {
Intent appInfo = new Intent(MainActivity.this, DisplayInfo.class);
User temp= users.get(position );
userSelected =new User(temp.first_name ,temp.last_name,temp.adr,temp.url );
startActivity(appInfo);
}
});
}
}
My second one (where the user inputs the info :
public class NewEmployeeInfo extends AppCompatActivity {
public ImageView imageview;
public ImageView targetImage;
public User u;
public static Bitmap photo;
public static Uri targetUri;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_employee_info);
}
public void takePhoto(View view) {
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, 0);
}
public void pickphoto(View view) {
Intent pickPhoto = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto, 1);
}
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
imageview = (ImageView) this.findViewById(imageView);
resultphoto(requestCode, resultCode, imageReturnedIntent);
}
public void Save(View view) {
Intent SaveDataIntent = new Intent(this, MainActivity.class);
EditText FN = (EditText) findViewById(R.id.editText);
EditText LN = (EditText) findViewById(R.id.editText5);
EditText ADDRESS = (EditText) findViewById(R.id.editText6);
String firstname = FN.getText().toString();
String lastname = LN.getText().toString();
String address = ADDRESS.getText().toString();
if (firstname.length() == 0 || lastname.length() == 0 || address.length() == 0) {
Toast.makeText(this, "No Emty Fields!!",
Toast.LENGTH_LONG).show();
return;
}
u = new User(firstname, lastname, address, targetUri);
users.add(u);
setResult(RESULT_OK, SaveDataIntent);
finish();
}
private void resultphoto(int requestCode, int resultCode, Intent imageReturnedIntent) {
switch (requestCode) {
case 0:
if (resultCode == RESULT_OK) {
targetUri = imageReturnedIntent.getData();
imageview.setImageURI(targetUri);
imageReturnedIntent.getExtras().get("data");
}
break;
case 1:
if (resultCode == RESULT_OK) {
targetUri = imageReturnedIntent.getData();
targetImage = (ImageView) findViewById(imageView);
try {
photo = BitmapFactory.decodeStream(getContentResolver().openInputStream(targetUri));
targetImage.setImageBitmap(photo);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
break;
}
}
}
the third and final one(Where the info should be displayed)
public class DisplayInfo extends AppCompatActivity {
public ImageView imageView;
public Bitmap image;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_info);
TextView fn = (TextView) findViewById(R.id.firstname);
TextView ln = (TextView) findViewById(R.id.lastname);
TextView adr = (TextView) findViewById(R.id.address);
imageView = (ImageView) findViewById(R.id.imageView2);
fn.setText(MainActivity.userSelected.first_name);
ln.setText(MainActivity.userSelected.last_name);
adr.setText(MainActivity.userSelected.adr);
imageView.setImageURI(MainActivity.userSelected.url ) ;
This error keep showing up

My problem was in the Manifest file;
It was
<application

android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"

<uses-permission

I misplaced my permissions. It should've been like this

Application restart if i changed the launcher activity in XML manifest

I have a funny problem, I have my project act wired, am following some tutorials and copied some codes, but now I figured that I cannot put any of my activities as launcher activity except the main activity , I looked really deep in it and didn't find anything that make it the only activity that fits to be the launcher activity , is it a manifest problem ? or special flag in the main activity ??!!

'class' or 'interface' expected in AndroidManifest.xml

I keep getting this build error 'class' or 'interface' expected. Everything I'm finding on SO is saying that my Java class is missing (or has an extra) a "}" I'm getting this error in my AndroidManifest.xml for all my Java activities. Here is the Java code:

Try a period before MainActivity where it's declared in the manifest.

Android: startActivity() works for one activity but not another

Part of an app I'm working on has two buttons, and my problem is that when I call startActivity() it will work as expected for one activity but not another.
So this works:
startActivity(new Intent(StartScreenActivity.this, FiltersActivity.class));
But this does not:
startActivity(new Intent(StartScreenActivity.this, MainActivity.class));
Both worked fine yesterday, but since updating Android Studio this morning nothing happens when I try to start MainActivity. Both are present in my manifest:
<activity
android:name=".FiltersActivity"
android:label="#string/title_activity_filters"
android:theme="#style/AppTheme.NoActionBar" >
</activity>
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main"
android:theme="#style/AppTheme.NoActionBar" >
</activity>
There are no errors thrown to the LogCat or anything like that, simply one works and nothing happens for the other. I would assume something is wrong with the MainActivity class, but it worked fine until a few hours ago and the only changes since then have been updating Studio, as I mentioned, and some small xml layout changes to the main activity layout file which I have tried undoing but that doesn't fix the problem.

Change your <activity> in manifest with:
<activity
android:name=".FiltersActivity"
android:label="#string/title_activity_filters"
android:theme="#style/AppTheme.NoActionBar" >
<intent-filter>
<action android:name="me.theglassboard.vee.FiltersActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main"
android:theme="#style/AppTheme.NoActionBar" >
<intent-filter>
<action android:name="me.theglassboard.vee.MainActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

Try the follow:
reference your button like this:
mButton1 = (Button) findViewById(R.id.button_1);
mButton2 = (Button) findViewById(R.id.button_2);
call your button with onClickListener
mButton1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent button1 = new Intent(StartScreenActivity.this, FiltersActivity.class);
startActivity(button1);
}
}
mButton2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent button2= new Intent(StartScreenActivity.this, MainActivity.class);
startActivity(button);
}
}
if not working, send printout of the MainsActivity.class and StartScreenActivity

Intent Activity not working

I'm doing a basic activity of moving from one page to another. Everything was going perfect until I get two pages deep into the app. I used the same exact code for each page class, put the activities in the manifest and made sure all words were spelled correctly, etc., but the intent doesn't do anything when I try to go three pages deep. There are no error messages in the log at all. When I click on a button on the third page, it just turns blue but doesn't move to the next page like the previous pages. Here's my code:
from page 1 to 3:
Page1:
public class MainActivity extends ActionBarActivity {
Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addListenerOnButton(); }
public void addListenerOnButton() {
final Context context = this;
button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, MainMenu.class);
startActivity(intent);
}
});
}
}
Page 2: has more buttons...
public class MainMenu extends ActionBarActivity {
Button button;
Button button2;
Button button3;
Button button4;
Button button5;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_menu);
addListenerOnButton();
}
public void addListenerOnButton() {
final Context context = this;
button = (Button) findViewById(R.id.button1);
button2 = (Button) findViewById(R.id.button2);
button3 = (Button) findViewById(R.id.button3);
button4 = (Button) findViewById(R.id.button4);
button5 = (Button) findViewById(R.id.button5);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, OneMain.class);
startActivity(intent);
}
});
button2.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, TwoMain.class);
startActivity(intent);
}
});
button3.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, ThreeMain.class);
startActivity(intent);
}
});
button4.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, FourMain.class);
startActivity(intent);
}
});
button5.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, FiveMain.class);
startActivity(intent);
}
});
}
}
Page 3:
public class OneMain extends ActionBarActivity {
Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.one_main);
}
public void addListenerOnButton() {
final Context context = this;
button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, Alphabet.class);
startActivity(intent);
}
});
}
}
I also made sure I put in all the imports. Someone help. I'm stuck :(.
Here is the manifest xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.juwar74.alarabic"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity android:name=".MainActivity"
android:label="#string/app_name"
android:launchMode="singleTop"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:label="#string/app_name"
android:name=".MainMenu" >
</activity>
<activity
android:label="#string/app_name"
android:name=".OneMain" >
</activity>
<activity
android:label="#string/app_name"
android:name=".TwoMain" >
</activity>
<activity
android:label="#string/app_name"
android:name=".ThreeMain" >
</activity>
<activity
android:label="#string/app_name"
android:name=".FourMain" >
</activity>
<activity
android:label="#string/app_name"
android:name=".FiveMain" >
</activity>
<activity
android:label="#string/app_name"
android:name=".OneVoc" >
</activity>
</application>
</manifest>
And here is the code for the Alphabet.class
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
public class Alphabet extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.alphabet);
}
}

in page3 you never called addListenerOnButton() .
public class OneMain extends ActionBarActivity {
Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.one_main);
// HERE you missed addListenerOnButton();
}

<activity
android:name=".Alphabet " >
</activity>
You missed this in the manifest.xml

First call addListenerOnButton() in OneMain.java after setContentView.
Then check manifest.
Alphabet.class is not registered in manifest.
<activity
android:label="#string/app_name"
android:name=".Alphabet" >
</activity>
After adding it, make sure you are rendering correct xml in Alphabet.java
