Android - How to configure VPN programatically? Jeff Sharkey » Modifying the Android logcat stream for full-color debugging. I’ve been keeping busy writing all sorts of fun stuff lately, but a few weeks ago I was really fighting with Android’s logcat debugging stream.

Jeff Sharkey » Modifying the Android logcat stream for full-color debugging

It dumps out tons of useful information, but it’s easy to get lost in the flood of text. So I whipped up a quick Python script that reformats the logcat output into a colorful stream that is much easier to visually follow. One feature I really like is that it allocates unique colors for each “tag” used. This makes it really easy to visually separate dozens of tags into their source apps, and makes it easy to pick your app out in the crowd. This was inspired by the irssi nickcolor script, and the best way to explain is using an example: There, isn’t that better? $ adb logcat | ~/ $ ~/ To keep things simple, it assumes you’re using an ANSI-compatible terminal (most xterms are fine), and it uses a quick hack to detect your column width for wrapping.

Android Development: More Than a Lot of Google Maps Markers

Basically, Google Maps can render only a limited number of markers over the map, let’s say a few thousand, but with larger numbers it will start to lag and will ruin the user experience. GenyMotion. Android-screen-monitor - Android Screen Monitor. The Android Screen Monitor (ASM) is a tool to monitor screen on the device or emulator.

Read More 2] AppXplore: With the AppXplore tool, you can go through all the apps installed on your Android device and dissect many application details – app version, package names, certificates, permissions, signatures, activities, and lots of other information that would not be normally viewable from the device. AppXplore is especially useful for seeing how much memory an app is using, and if the file is movable to the SD card.

Likewise, developers can use AppXplore for testing and quality assurance purposes, to make sure their apps are showing the proper permissions in the manifest file. Read More Read More. Device Metrics - Google Design. Google Proximity Beacons - Part 2 - NewCircle. The following discussion relates to library code available in Google Play Services v7.8.

Google Proximity Beacons - Part 2 - NewCircle

If you are using later versions of Play Services, the API surface area may have changed since this article was written. We saw in the previous post how Google's Proximity Beacon API could be used to create and attach additional contextual data to the otherwise simple advertisement of a Bluetooth beacon. In this post, we are going to dive deeper into the client side. How do we get our user's devices to recognize these beacons and retrieve the information created by the beacon management admin?


Android-OpenCV. How to Customize Android UI Components. It is not uncommon for developers to find themselves in need of a UI component that is either not provided by the platform they are targeting or is, indeed, provided, but lacks a certain property or behavior.

How to Customize Android UI Components

The answer to both scenarios is a custom UI component. The Android UI model is inherently customizable, offering the means to create custom UI components in various ways: Inherit an existing component (i.e. TextView, ImageView, etc.), and add/override needed functionality. Getting Started. Android Design Support Library. Posted by Ian Lake, Developer Advocate Android 5.0 Lollipop was one of the most significant Android releases ever, in no small part due to the introduction of material design, a new design language that refreshed the entire Android experience.

Android Design Support Library

Our detailed spec is a great place to start to adopt material design, but we understand that it can be a challenge for developers, particularly ones concerned with backward compatibility. With a little help from the new Android Design Support Library, we’re bringing a number of important material design components to all developers and to all Android 2.1 or higher devices.

Creating a Navigation Drawer. The navigation drawer is a panel that displays the app’s main navigation options on the left edge of the screen. It is hidden most of the time, but is revealed when the user swipes a finger from the left edge of the screen or, while at the top level of the app, the user touches the app icon in the action bar. This lesson describes how to implement a navigation drawer using the DrawerLayout APIs available in the Support Library. Navigation Drawer Design Before you decide to use a navigation drawer in your app, you should understand the use cases and design principles defined in the Navigation Drawer design guide.

Kirill Grouchnikov - Google+ - Now that we've talked about enabling the action bar overlay… Now that we've talked about enabling the action bar overlay mode [0] and doing parallax scrolling effects [1], it's time to take a look at the integration between action bar overlays and the side drawer [2]. If you don't use side drawer in your app, you can stop reading now. First up, you're going to need to set explicit top padding on the layout you're using for the side drawer content. As mentioned in [0], once you enable the action bar overlay mode, your main content goes below the action bar. Your main layout would be either DrawerLayout or an extension of that class.

[This post is by Patrick Dubroy, an Android engineer who writes about programming, usability, and interaction on his personal blog. — Tim Bray] The Dalvik runtime may be garbage-collected, but that doesn't mean you can ignore memory management. You should be especially mindful of memory usage on mobile devices, where memory is more constrained. In this article, we're going to take a look at some of the memory profiling tools in the Android SDK that can help you trim your application's memory usage.

Some memory usage problems are obvious. For example, if your app leaks memory every time the user touches the screen, it will probably trigger an OutOfMemoryError eventually and crash your app.
