I've added the correct permission into my AndroidManifest.XML file to enable me connect to the internet from my app
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.my_test_app">
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".LogOn"></activity>
<activity android:name=".ftpDetails"/>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
But, when trying to establish an FTP connection like so
FTPClient FtpClient = new FTPClient();
FtpClient.connect(ftpServer + ftpFolder); // THIS IS WHERE THE ERROR OCCURS
FtpClient.login(ftpUser, ftpPass);
int reply = FtpClient.getReplyCode();
The error occurs on FtpClient.connect(ftpServer + ftpFolder);
The values in the variables are in the format of
ftpServer = ftp://ftp.myServer.co.uk/mySite.co.uk/
ftpFolder = My Folder (Test)
I can get to this folder through Windows File Explorer on my PC so I know it's a valid path, but when testing in the app I get the following error
Unable to resolve host "ftp://ftp.myServer.co.uk/mySite.co.uk/My Folder": No address associated with hostname
The argument of FTPClient.connect method (or actually the inherited SocketClient.connect) is hostname, not URL.
So it should be:
ftpServer = "ftp.myServer.co.uk";

What should i add here for the scheme for URl redirect, can i add anything, like "com.example.oauth/:oauth2redirect"(Package name:/ oauth2redirect)?.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.oauth">
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.INTERNET">
</uses-permission>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.Oauth">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<data android:scheme=" ">
</data>
</intent-filter>
The most common option when learning Mobile OAuth is to start with a value like this, using a reverse DNS style of naming, to include your company + app names:
com.mycompany.myapp:/callback
A good starting point for something to compare against is the Android AppAuth Code Sample, where you just specify a scheme value in the gradle file.
If it helps, my Blog Post has some step by step instructions to get the sample running.

This is because DecimalFormat generate localized string, and the decimal separator can be different in some locale.
You can force the good locale like this :
DecimalFormat precision = new DecimalFormat("0.00", new DecimalFormatSymbols(Locale.US));
More info here
From your stacktrace there is error in Real number format in method of your MainACtivity onSensorChanged with value "9,35". In java all floating numbers use dot like this "9.35". Check this method and use correct format of Real number
I'm trying to integrate flurry into my android app. I'm using the recommended setting and have repositories{jcenter()} and
// Required for Flurry Analytics integration
compile 'com.flurry.android:analytics:8.2.0#aar'
// Optional - If you want to use the Ads SDK
compile 'com.flurry.android:ads:8.2.0#aar'
in the gradle as the docs suggest. I keep getting errors in the that Application is not resolved. The docs really blow and I'm not 100% sure what going on. I've never integrated flurry before can someone please help! I put the manifest and the class i'm using below. I know it doesn't have a key I'm still working on removing errors. I'm dumping the that class in the main file for simplicity for now.

I have been implementing the code of login and registration app from http://www.androidhive.info/2012/01/android-login-and-registration-with-php-mysql-and-sqlite/
I copy pasted the code along with following the instructions but I am still getting the registration error : null in the log cat on pressing the register button.
The php files(ex: register.php) are displaying {"error":true,"error_msg":"Required parameters (name, email or password) is missing!"} , that means they are working fine.
I am using xampp and have kept the files in htdocs. I have checked various url in Appconfig.java such as 127.0.0.1, 10.0.2.2:8080, 10.0.2.2:80, and the ip of my computer system from ipconfig cmd, but still getting same error.
Here is the code of Appconfig.java.
package com.urjapawar.hackathon1;
public class AppConfig {
// Server user login url
public static String URL_LOGIN ="http://192.168.2.5/android_login_api/login.php";
// Server user register url
public static String URL_REGISTER = "http://192.168.2.5/android_login_api/register.php";
}
and here is the code of Android manifest:

I am having a problem integrating the AmazonS3PersonalFileStore demo app login into my App
I have set up my TVM and everything works fine on the demo app, it also runs correctly when I copy/paste the project and rename it.
The issue comes when I begin pasting my .javas from my main app into the pasted Demo app, now when I login, I get the error

Although I have added new code, I am pretty sure that none of it is running, since none of my activities are being created
Update: I tried adding an EC2 role to the TVM Elastic Beanstalk with the same permissions as the IAM TVMUser, but the demo app wouldn't even work
Update 2: Tried a bunch of different IAM configurations for the TVM IAM User / Elastic Beanstalk, nothing worked
I had the same issue when integrating the AmazonS3PersonalFileStore demo app login into my app.
The problem was that the request to the TVM via the HTTP request was blocked. This is due to the android sdk's StrictMode.ThreadPolicy which does not allow network operations to execute on the UI thread.
This restriction can be changed, using:
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
Add the above code into your main activity's onCreate() method.
In addition, it is always recommended to move network operation off the UI thread, for example, using AsyncTask.
I am confident this will fix your problem.
