Why do my test results vary? All of the devices between your computer and the server where the speed test resides can play a role in this. Each computer, switch, router, and server in the path can affect your results. Since your computer and the network are constantly changing your results may be impacted. What speeds should I expect? Pushing the data to the server over the network via multiple streams ensures that the maximum throughput is measured.
Again, recording the data throughput against time yields the available internet speed for uploading data. During the ping test, the device sends a small data package over the network to the test server on the internet. When the server receives this package, it will send it back to the device, completing the roundtrip. The time it takes the data package to complete the roundtrip is called latency, also known as ping. To achieve an accurate reading, multiple ping tests are conducted consecutively, with the final result being the average of all these tests.
All these are automatically handled for you when using Speedcheck. But you should take one crucial aspect into account to test speed accurately. Choose the right tool. This depends on the device you want to use, being a phone or tablet, or a computer.
To check internet speed on a computer, use your browser and the app on this website. To achieve accurate results on mobile devices, you should download our iOS or Android app, respectively. This is especially important when running a WiFi speed test. Because browsers on mobile devices have poor performance, we suggest using a mobile app written in native code to ensure the most accurate speed test results. This is explained in the table below:.
The files AAPT2 outputs are not executables and you must later include these binary files as input in the link phase to generate an APK. However, the generated APK file is not an executable that you can deploy on an Android device right away, as it does not contain DEX files compiled bytecode and is not signed. In the following example, AAPT2 compiles resource files named values. As shown in the table above, the name of the output file depends on the input file name and the name of its parent directory the resource type and configuration.
For the example above with strings. There are several options that you can use with the compile command, as shown in the table below:. This is a required flag because you must specify a path to a directory where AAPT2 can output and store the compiled resources.
Although you can use this flag to compile multiple resource files with one command, it disables the benefits of incremental compilation and thus, should not be used for large projects. Use this option if you have already processed the PNG files, or if you are creating debug builds that do not require file size reduction. Enabling this option results in a faster execution, but increases the output file size.
This flag should be used for unexpected compile time errors. Additionally, other auxiliary files like R. That is, you can't deploy this APK to a device. If you're not using the Android Gradle Plugin to build your app from the command line , you can use other command line tools, such as d8 to compile Java bytecode into DEX bytecode and apksigner to sign your APK.
AAPT2 links the result against android. This is a required flag because you must specify the path for the output APK that can hold the linked resources. This is a required flag because the manifest file encloses essential information about your app like package name and application ID. You can use this directory to store original unprocessed files. To learn more, read Accessing original files.
When you a provide a resource file that overlays extends or modifies an existing file, the last conflicting resource given is used. The package ID that you specify must be greater than or equal to 0x7f unless used in combination with --allow-reserved-package-id. Reserved package IDs are IDs that are normally assigned to shared libraries and are in the range from 0x02 to 0x7e inclusive. By using --allow-reserved-package-id , you can assign IDs that fall in the range of reserved package IDs.
For example, if you have dependencies on the support library which contains translations for multiple languages , you can filter resources just for the given language configuration, like English or Spanish. You must define the language configuration by a two-letter ISO language code, optionally followed by a two letter ISO alpha-2 region code preceded by lowercase 'r' for example, en-rUS.
There are several pixel density qualifiers available to use in your app, such as ldpi, hdpi, and xhdpi. When you specify a preferred density, AAPT2 selects and stores the closest matching density in the resource table and removes all others. Suitable as input to the bundle tool for generating an Android App Bundle. This option allows assigned IDs to remain stable even when you delete or add new resources while linking. It should be used in conjunction with --rename-manifest-package.
For example, the following command prints content from the resource table of the specified APK:. You need to specify one of the following sub-commands with the dump command:. Although AAPT2 should immediately work with older projects, this section describes some behavior changes that you should be aware of.
In previous versions of AAPT, elements nested in incorrect nodes in the Android manifest were either ignored or resulted in a warning. When providers host their own speed tests they eliminate the variables that you're here to test.
Namely the Internet route itself. This test is unbiased, it tests and grades all providers on the same criteria.
