Android Menifest permission are:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

DELETE with body can lead to unexpected behavior. Per HTTP/1.1 RFC2616, this is neither allowed not disallowed. However, depending on which HTTP library you use, the behavior may vary. As for the generated API Gateway client, its uses HttpURLConnection as recommended by Android. Nevertheless, the implementation of HttpURLConnection is platform dependent. Priory to API level 19, it's close to Java's standard implementation by Sun, where ProtocolException will be thrown on DELETE with body. Since API level 19, Android switches to OkHttp which permits such behavior (see https://github.com/square/okhttp/issues/605). This should explain why it works on some place but not the other. In summary, I suggest you avoid defining an API which does DELETE with body.

App crashing on particular Android version

I am working on an Android application. when I run my App below api 16 it works fine but when it runs on a post api 16 phone it crashes. Here is a the logact log which appears when it crashes.

As you are using some deprecated features, so it may not supported for some API levels. For this you can check the api level as well as version before using the deprecated features using if condition. For example :
if(Build.VERSION.RELEASE.equals("4.4.4")) {
//Do somthing
}

Can't install apps with Eclipse ADT on my phone

I would like to install and debug projects using Eclipse ADT. It finds the device and trys to install but then I get the errors below.
The phone is a "HTC One S" and it is the Custom ROM "Codename Lungo One S" (4.3). The applications are the Kontalk project and the ApiDemos from the 17 (4.2.2) samples both build for 4.2.2.
Installing in the emulator works.

Any ideas? Can't find anything on this on the internet?

You can try the
<uses-permission android:name="android.permission.INSTALL_PACKAGES" />
before the application tag is start in the AndroidManifest.xml.

I think you are looking for this but you can try clean and build your project first.

The problem is Codename Lungo with CM10.1 and CM10.2. This is a bug or at least you can't debug Apps with the standard procedure. It works on my phone with CL CM10 and CynogenMod 10.2.
Tim Veluwenkamp announced a new version of CL yesterday that may address the issue but I am not sure about it. I am on CM10.2 now.

When i run the application from eclispe i dont get any of this error and everyting just running fine.
I think its the pro guard i added the my app but im not sure.
Here is my pro gurad settings:
proguard-project.txt:
# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:

File write permission error in Android

I am writing a file to SDCard and set <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> it works good upto 3.x but on 4.0 it gives the below error.

Any help or suggestion?

Just guessing but did you probably have your phone still connected to the computer? This error might happen if your sd card is still locked as a usb device.
Hope this helped,

Latter on I discovered that the issue is device specific. I installed the File Manager app from Android market and it shows no write permission. It mean the Android OS implementation of that manufacturer do not provide write permission which is causing the issue.

Probably you have hard-coded the external storage directory and it works on particular devices.
Environment.getExternalStorageDirectory();
Posting your code will help much more than just the log.

You may check you've just updated your Android O/S, too. Some major change cause sdcard problem. For me, I update my Android O/S in SHV-E160K from 2.3.5 to 4.1.2 with Odin which is samsung firmware update application. And I faced problem.
My detailed error message is as follows :

The reason is 4.1.2 couldn't recognize file system in 2.3.5. I solve this formatting sdcard storage. format doesn't mean delete your personal information such as address, memo or history. After format, it works like magic.

This may help you.
I faced the same issue when writing the file on sdcard. I have set all required permission to write the file but i used file object like below:
Wrong :
File myFile = new File(Environment.getExternalStorageDirectory().getAbsoluteFile()+fileName);
Correct:
File myFile = new File(Environment.getExternalStorageDirectory().getAbsoluteFile(), fileName);
That means the path was wrong.
