I have been trying to remove all the logs on the device through this code:
contentResolver.delete(CallLog.Calls.CONTENT_URI,null,null);
But it only deletes Call Logs, and SMS logs still remain undeleted.
How delete all the logs including SMS logs?
Any help would be appreciated..!!
getContext().getContentResolver().delete(
Uri.parse("content://sms/conversations/" + threadID),
null,
null);
try this
You can remove all smslog using this way.
getContentResolver().delete(Uri.parse("content://sms/"),null,null);
for Deleting SMS from your smslog need uses permission declared in your manifest
<uses-permission android:name="android.permission.READ_SMS"/>
<uses-permission android:name="android.permission.WRITE_SMS"/>

I'm following the File transfer example on the Nearby Connections Exchange page (the "more complex example" code snippet).
I can send an image and receive it on another device in the Download/Nearby folder. The image is sent successfully since if I were to change the file name to give it an appropriate extension (e.g. .jpg), I can open the image in a photo gallery app.
private void processFilePayload(long payloadId) {
Payload filePayload = completedFilePayloads.get(payloadId);
String filename = filePayloadFilenames.get(payloadId);
if (filePayload != null && filename != null) {
completedFilePayloads.remove(payloadId);
filePayloadFilenames.remove(payloadId);
// Retrieve received file from Downloads folder
Payload.File payloadFile2 = filePayload.asFile();
File payloadJavaFile = payloadFile2.asJavaFile();
if (payloadJavaFile == null) {
Log.d(TAG, "Payload java file is null in processFilePayload()");
} else {
payloadJavaFile.renameTo(new File(payloadJavaFile.getParentFile(), filename));
}
}
}
Why is the payloadJavaFile variable null? From looking at Payload.class, I know that the result of asJavaFile() is a nullable File and that, from the asJavaFile() method description, calling asJavaFile() in processFilePayload() from within onPayloadReceived() (as is done in the example on the API page) may lead to the File not having received all of the payload's contents yet. However, I also call processFilePayload() from within onPayloadTransferUpdate() after verifying the success of the PayloadTransferUpdate, and so shouldn't the payload have received all of its contents by this stage (and not be null when calling asJavaFile() on the payload object)?
My code is almost the same as the documentation for both sending and receiving the image and file name.
Payload.asJavaFile() will be null if the READ_EXTERNAL_STORAGE permission is not properly set up for your application. You need READ_EXTERNAL_STORAGE in the AndroidManifest.xml and you need to also request READ_EXTERNAL_STORAGE permission at runtime since it is a dangerous permission. (https://developer.android.com/training/permissions/requesting)
To share files using Nearby Connections, your application will need all of the following:
AndroidManifest.xml
<!-- Required for Nearby Connections -->
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<!-- Optional: needed to share files -->
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
MainActivity.java
ActivityCompat.requestPermissions(thisActivity,
new String[]{
Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.READ_EXTERNAL_STORAGE
},
PERMISSIONS_REQUEST_CODE);
We will improve the documentation to make this requirement for sharing files more obvious.
I checked the source code. From what I can see, asJavaFile() is always set (and I'm not sure why it's marked as #Nullable).
Unfortunately, for me to look into it any further, I'd need you to provide me with a sample app that reproduces the bug you're seeing.
Im facing a big problem, Im trying to connect to an URL using a GET method. It give me an error java.net.UnknownHostException: Unable to resolve host "URL": No address associated with hostname.
I have been reading some post and all people say it is about permissions.My permissions are:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
I can access to that URL by using chrome in my mobile, it means that wifi is working.
I am using a Motorola g 2, API 23.
Printing the response on the Log ?
Did you try switching of the WiFi or phone or both and tried again ?
This problem can occur when you are on VPN. I had a similar issue. After disconnecting from the VPN I tried connecting again. It got connected.
Also try rechecking the URL since the UnknownHostException is popping up there is high possibility that the URL string you are passing in the program(URL class probably) is wrong.
Hope it helps.
You have two solutions for your problem. The quick one is to lower targetApi to 22 (build.gradle file). Second is to use the new runtimePermission model:
Since your target api is 23 you should add the permissions on runtime too.
if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.INTERNET) {
// Should we show an explanation?
if (shouldShowRequestPermissionRationale(
Manifest.permission.INTERNET)) {
// Explain to the user why we need to read the contacts
}
requestPermissions(new String[]{Manifest.permission.INTERNET},
MY_PERMISSIONS_REQUEST_INTERNET);
// MY_PERMISSIONS_REQUEST_INTERNET is an
// app-defined int constant
return;
}

I have an app that, due to lack of mobile data in all areas, uses phone connection to make a phone call. There is some important information on the screen in my app, so I want to place the call without leaving my app screen. Is there any way to do this?
Add the following permission in mainfest file
<uses-permission android:name="android.permission.CALL_PHONE" />
Use the below code to start calling
Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "123456789" ));
startActivity(intent);
If you want to implement inside tha app read the tutorial which will help you alot
I'm trying to create a simple app that can get an image from the Gallery app and display it on an imageButton. I'm testing with API 21 on a phone running Android 5.0.1. Unfortunately, no matter what I try I keep getting a security error - even when I specify the permissions.
My code for getting retrieving the image is:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent){
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode){
case PICK_IMAGE_REQUEST:
if(resultCode == RESULT_OK && imageReturnedIntent != null && imageReturnedIntent.getData() != null) {
Uri uri = imageReturnedIntent.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
// Log.d(TAG, String.valueOf(bitmap));
ImageButton ib = (ImageButton) findViewById(R.id.inputImg);
ib.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
break;
}
}
The code works when I try to select an image from Dropbox, but when I select an image from gallery, I get
java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/images/media/35634 from pid=25240, uid=10070 requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission()
I made the use-permission tag for READ_EXTERNAL_STORAGE a child of manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="[REDACTED]">
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="23" />
<uses-permission tools:node="replace" android:name="android.permission.READ_EXTERNAL_STORAGE" android:maxSdkVersion="18" />
<application>
[REDACTED]
</application>
</manifest>
I've searched high and low on other posts, but still can't seem to figure out why I'm still getting this pesky error.
PROBLEM
Your have the error
java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/images/media/35634 from pid=25240, uid=10070 requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission().
CAUSE
You are not giving correctly permissions because of android:maxSdkVersion="18", which according to documentation.
The highest API level at which this permission should be granted to your app. Setting this attribute is useful if the permission your app requires is no longer needed beginning at a certain API level.
As long as you didn't give permissions to API 21 your app is behaving ok.
Check this topic for further info.
SOLUTION
If you wanna give read permissions under API 21, you must declare them as:
<uses-permission
android:name="android.permission.READ_EXTERNAL_STORAGE"
android:maxSdkVersion="21" />
IMPORTANT:
This only make sense when you need to give extra permissions because some old api's require permissions that new versions doesn't, so user experience get's improved because you only ask for certain permissions when needed.
So (in this case) the correct way will be:
<uses-permission
android:name="android.permission.READ_EXTERNAL_STORAGE" />
ADD ON
If you want to save data you must add WRITE_EXTERNAL_STORAGE permissions.
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Simply replace with the below one and try,
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
While debugging on some devices you need to grant permission explicitly by going to your settings --> apps --> MY_APPLICATION --> Permissions and then grant required permissions.
In addition to adding the below in AndroidManifest.xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
we also need to request permission in the activity for the app to actually have access to external storage. https://developer.android.com/training/permissions/requesting.html
I declared these two variables in order to send a text message to declared number:
private String text="Hi";
private String emergencyNum="00962789113300";
Then in onCreat() method I wrote this:
SmsManager sender= SmsManager.getDefault();
sender.sendTextMessage(emergencyNum, null, text, null, null);
Unfortunately, the message was not sent and I got not responding status for my app. Could you help me to solve the problem.
Please place the following permission into AndroidManifest.xml file.
<uses-permission android:name="android.permission.SEND_SMS"/>
