android.content.ActivityNotFoundException: passing url to the intent

Code with error:
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://m.fretebras.com.br/fretes"));
startActivity(i);
The error occurs in versions 6.0.1 android, I have no idea why it's happening, I believe that by passing the url to Intent is all right. Can someone help me?

Seems like no browser installed on your phone. Please verify and to avoid crash use below code.
try {
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://m.fretebras.com.br/fretes"));
startActivity(i);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
Note - This code will just ignore your crash, if no browser found.

Enable WiFi in AlertDialog crashes

If wifi or mobile data is not enabled, it should ask the user, if he clicks yes in the AlertDialog, it will go to the settings.
This is inside main, on create, when the update button clicked:
btnUpdate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.v(TAG,"ButtonUpdate clicked");
connectIfNecessary();
currentDate = Calendar.getInstance();
formatter= new SimpleDateFormat("yyyy-MM-dd");
new UpdateDB(MainActivity.this);
txtLastUpdateShow.setText(formatter.format(currentDate.getTime()));
});
This is connectifnecessary:
public void connectIfNecessary(){
Log.v(TAG, "main connectIfNecessary");
if(!isConnected()){
final Context ctx = this;
AlertDialog.Builder builder = new AlertDialog.Builder(ctx);
builder.setCancelable(true);
builder.setMessage("need internet");
builder.setTitle("do you want to enable it now?");
builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
ctx.startActivity(new Intent(Settings.ACTION_WIRELESS_SETTINGS));
}
});
builder.setNegativeButton("no", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
return;
}
});
builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
public void onCancel(DialogInterface dialog) {
return;
}
});
builder.show();
}
}
this is isConnected:
public boolean isConnected(){
Log.v(TAG, "mainisconnected");
ConnectivityManager conectivtyManager = (ConnectivityManager)
getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
if (conectivtyManager.getActiveNetworkInfo() != null
&& conectivtyManager.getActiveNetworkInfo().isAvailable()
&& conectivtyManager.getActiveNetworkInfo().isConnected()) {
Log.v(TAG, "mainisconnected true");
return true;
} else {
Log.v(TAG, "mainisconnected false");
return false;
}
}
in updatedb constructor, it will call asynctask to connect websites.
When i run this, and click update button, it crashes because it goes into updatedb withpout asking me in builder. The errors:

MainActivity.java:106) is builder.show()
MainActivity.java:276) connectIfNecessary();
I am getting errors for hours, at first about appcompat, then manifest then layout now this.
I use real tablet device.

When device is not connected , following would be execution flow
Get inside connectIfNecessary()
Create Alert to ask user to enable internet. Please note that only Alter object is created at this moment, it will be displayed on screen only after stack of main thread unwinds.
Return from connectIfNecessary() create instance of updateDB(). Inside this application is crashing
Few simple changes would fix your code.
add isConnected() if check before creating instance of updateDB(). This will cover the CONNECTED case
if the device is NOT CONNECTED, user will shown the alter and take to settings screen. If user enables WIFI from settings and comes back, onResume() of your activity will be called. Check connectivity and add updateDB() here.

NullPointerException when I try to capture an image (built-in camera) and save it to a file [duplicate]

This question already has answers here:
Android Camera : data intent returns null
(11 answers)
Closed 8 years ago.
Here's what the app does - User clicks button (to take a picture) on Activity A, the captured image gets set as on an ImageView in Activity A, and then the user clicks a "save" button, which takes him/her to Activity B, where the image they took gets displayed (on an ImageView in Activity B)
In order to do this I am trying to find a way to save the image. I tried many different things, but I keep getting a NullPointerException. Here is my code:
I highlighted the area where I think the error is:
public void onClick(View view) {
switch (view.getId()) {
case R.id.take_picture_button:
takePic = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
if (takePic.resolveActivity(getPackageManager()) != null) {
File photoFile = null;
try {
photoFile = createImageFile(); //so photoFile = the file we created up top
} catch (IOException ex) {
// Error occurred while creating the File
ex.printStackTrace();
}
// Continue only if the File was successfully created
if (photoFile != null) {
**takePic.putExtra(MediaStore.EXTRA_OUTPUT**, //extra_output is just the name of the Intent-extra used to indicate a content resolver Uri to be used to store the requested image or video.
**Uri.fromFile(photoFile));**
startActivityForResult(takePic, cameraData);
}
And here is the code for the onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == cameraData && resultCode == RESULT_OK) {
mReturningWithResult = true;
extras = data.getExtras();
And here is where I set my image view to my captured image (on Activity A)
#Override
protected void onPostResume() {
super.onPostResume();
if (mReturningWithResult) {
foodImage = (Bitmap) extras.get("data");
foodImageView.setImageBitmap(foodImage);
}
mReturningWithResult = false;//resetting it for next time
}
Here is the logcat (sorry I'm new to this)

Do you guys know a way I can fix this? Thank you!

You are passing MediaStore.EXTRA_OUTPUT, in which case, the intent field in onActivityResult can be null.
The solution is to just use the photo file you created, and passed as uri in the putExtra
So instead of trying to get the photo file location from the intent, just use Uri.fromFile(photoFile)
replace
extras = data.getExtras();
...
with
`Uri.fromFile(photoFile)`
or just use photoFile if that is what you want...just dont rely on intent data

Activity crashes because of Intent with ACTION_SEND

I have an Intent to share a image from an view. It works, but once I canceled it to upload it on Instagram and I received an exception.
Google didn't help...
Intent
if(!getStringName().equals(" ")) {//check if it is usefull
LinearLayout table=(LinearLayout) findViewById(R.id.table_linear);
table.setDrawingCacheEnabled(true);
Bitmap bitmap = table.getDrawingCache();
String imagepath=saveBitmap(bitmap);
//sv.setDrawingCacheEnabled(false);
Intent shareImage=new Intent();
shareImage.setAction(Intent.ACTION_SEND);
shareImage.setType("image/png");
shareImage.putExtra(Intent.EXTRA_SUBJECT, getString(R.string.app_name));
shareImage.putExtra(Intent.EXTRA_TEXT, getStringName());
shareImage.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(imagepath)));
startActivity(shareImage);
//new RalaAlertToast(context, getString(R.string.share_success), false);
}else {
//show message, that it's not useful
}

Broadcast receiver, check a checkbox preference state on bootup then send a notification

My problem is that when I try to read a checkbox preference state from a different activity on bootup then send a status bar notification. Then when the device boots the I get a force close error message popup then when I go into the error log I don't understand what happens.
The code for the broadcast receiver is shown below:
#Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
//this creates a reference to my preferences activity
Prefs prefsC = new Prefs();
SharedPreferences prefs = context.getSharedPreferences("Prefs", 0);
int status = Integer.parseInt(prefs.getString("bootup", "-1"));
if(status > 0){
//notifyNS is a method that sends the status bar notification
prefsC.notifyNS("", R.drawable.n);
//the setCheckedNS method is just a custom method I made to set the state of a checkbox preference
prefsC.setCheckedNS("icon", false);
}else{
prefsC.setCheckedNS("enable", false);
prefsC.setCheckedNS("icon", false);
prefsC.setCheckedNS("bootup", false);
}
}
}
So could you help me solve the issue on why it force closes on bootup. So basically what I want to do is read a checkbox preference state on bootup then send a status bar notification.
This is my error log response:

So I have no clue what to do from here.
Alright I have figured out what I have done wrong. What it is how I was connecting the context to the notificationManger construct method and Intent construct method.
Here is my new and revised code that works:
`public class BootupReceiver extends BroadcastReceiver {
private static final boolean BOOTUP_TRUE = true;
private static final String BOOTUP_KEY = "bootup";
#Override
public void onReceive(Context context, Intent intent) {
if(getBootup(context)) {
Toast toast2 = Toast.makeText(context, "getBootup", Toast.LENGTH_SHORT);
toast2.show();
NotificationManager NotifyM = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification Notify = new Notification(R.drawable.n,
"NSettings Enabled", System.currentTimeMillis());
Notify.flags |= Notification.FLAG_NO_CLEAR;
Notify.flags |= Notification.FLAG_ONGOING_EVENT;
RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.notification);
Notify.contentView = contentView;
Intent notificationIntent = new Intent(context, Toggles.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
Notify.contentIntent = contentIntent;
Toast toast = Toast.makeText(context, "Notify about to be sent", Toast.LENGTH_SHORT);
toast.show();
int HELO_ID = 00000;
NotifyM.notify(HELLO_ID, Notify);
Toast toast1 = Toast.makeText(context, "Notify sent", Toast.LENGTH_SHORT);

Since this question has gotten more than 100 views I thought it would be nice of me to post the code that works properly.
Note: I don't know why the closing curly bracket for the class isn't showing with the rest of the code it's a stackoverflow error

According to log ('java.lang.RuntimeException: Unable to instantiate receiver'), system is unable to create instance of your receiver class, because system is unable to find specified class (com.brandon.labs.nsettings.receivers.notifyBootup). I think it is probably problems with name (of receiver class) in your AndroidManifest.xml file, and it is not related to preferences.
In future, if you will get another exception, i recommend you to read carefully message of exception ;) and stack trace. Usually they contains the half of answer to your question.
And for popular mistakes - you can try to type exception text into Google (excluding some specific info such as name of class), and you will find solution very fast.

Have you added the following to your AndroidManifest.xml along with registering the BroadcastReceiver??
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
