Open up any app in some kind of file viewer and take a look at it's contents, it has four folders:. Many games are very large in size, Infinity Blade for example is about 1. Honestly, I think it'd be very hard to get the executable itself above 60 MB. Like I said before, the bulk of app size is comprised of resources.
You may also want to refer to the iTunes Connect Guide here. The app bundle file structure and sandboxing system has changed in iOS 8 slightly. Therefore, some of the information about the structure of the app bundle above may be incorrect for iOS 8.
However, iOS will still calculate the size of each of these items and count them as your app's size. For example, in iOS 8, your app's documents may not be stored within your app bundle, however they still count towards the total storage space used by your app.
The size limit of an app package submitted through iTunes Connect has increased from 2 GB to 4 GB, so you can include more media in your submission and provide a more complete, rich user experience upon installation. Please keep in mind that this change does not affect the cellular network delivery size limit of MB.
No, you can add data to the app post installation. For instance, the app could simply display stuff from a database, like say a dump of wikipedia. The space you app executable would require would be small, but you could reach the 2GB limit with the database. If it exceeds 60 MB, you require special approval from Apple. Apple believes core logic of your code may not exceed 60 MB and the resources bundles can also be downloaded over the air as required, if your app supports multiple languages.
Over the air over cellular not wifi network limit is 50 MB. If your app is more than 50 MB you will get a warning that you will require a wifi connection to download the app. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Now, click on the option to download the app. The App Store will try to download the app, but will soon pop up an alert saying the app exceeds the MB limit on cellular data.
You must dismiss the alert. Next, manually set a date a few years into the future. Like for the year Now, you will get an App Store pop-up asking you to retry the download. Click on retry and you will notice that the app, which earlier failed is now downloading over the cellular data connection.
The app will download as normal. Bigger files as expected would take longer on the cellular network. This workaround to bypass the App Store download limit works perfectly, and has worked for all that have used it.
But, a drawback of this workaround is that it is just a bug. So, it might be that Apple will plug this loophole in the future. For the existing users, however, the iTunes renewal payment continues to work. Bypassing the App Store would allow Netflix to keep the entire proceeds from the new subscribers, and avoid paying a cut to Apple.
Android provides several utilities to change the color of an asset, either using the android:tint and tintMode attributes on Android 5.
For lower versions of the platform, use the ColorFilter class. You can also omit resources that are only a rotated equivalent of another resource. The following code snippet provides an example of turning a "thumb up" into a "thumb down" by pivoting at the middle of the image and rotating it degrees:. You can also reduce your APK size by procedurally rendering your images. Procedural rendering frees up space because you no longer store an image file in your APK.
For example, the aapt tool can convert a true-color PNG that does not require more than colors to an 8-bit PNG with a color palette. Doing so results in an image of equal quality but a smaller memory footprint.
Keep in mind that the aapt has the following limitations:. You can reduce PNG file sizes without losing image quality using tools like pngcrush , pngquant , or zopflipng. All of these tools can reduce PNG file size while preserving the perceptive image quality. The pngcrush tool is particularly effective: This tool iterates over PNG filters and zlib Deflate parameters, using each combination of filters and parameters to compress the image. It then chooses the configuration that yields the smallest compressed output.
You can use vector graphics to create resolution-independent icons and other scalable media. Using these graphics can greatly reduce your APK footprint. Vector images are represented in Android as VectorDrawable objects. With a VectorDrawable object, a byte file can generate a sharp image the size of the screen. However, it takes a significant amount of time for the system to render each VectorDrawable object, and larger images take even longer to appear on the screen.
Therefore, consider using these vector graphics only when displaying small images. For more information on working with VectorDrawable objects, see Working with Drawables. Do not use AnimationDrawable to create frame-by-frame animations because doing so requires that you include a separate bitmap file for each frame of the animation, which drastically increase the size of your APK.
Instead, you should use AnimatedVectorDrawableCompat to create animated vector drawables. Reduce native and Java code There are several methods you can use to reduce the size of the Java and native codebase in your app.
Make sure to understand the footprint of any code which is automatically generated. For example, many protocol buffer tools generate an excessive number of methods and classes, which can double or triple the size of your app. A single enum can add about 1. These additions can quickly accumulate for complex systems or shared libraries. If possible, consider using the IntDef annotation and code shrinking to strip enumerations out and convert them to integers.
This type conversion preserves all of the type safety benefits of enums. If your app uses native code and the Android NDK, you can also reduce the size of the release version of your app by optimizing your code. Two useful techniques are removing debug symbols and not extracting native libraries.
Using debug symbols makes sense if your application is in development and still requires debugging. Use the arm-eabi-strip tool, provided in the Android NDK, to remove unnecessary debug symbols from native libraries.
After that, you can compile your release build. When building the release version of your app, package uncompressed. Disabling this flag prevents PackageManager from copying. When building your app using Android Gradle plugin 3. Your APK might contain content that users download but never use, like additional language or per-screen-density resources. To ensure a minimal download for your users, you should upload your app to Google Play using Android App Bundles. If you're not publishing your app to Google Play, you can segment your app into several APKs, differentiated by factors such as screen size or GPU texture support.
When a user downloads your app, their device receives the correct APK based on the device's features and settings. This way, devices don't receive assets for features that the devices don't have.
