You Have Permission to Crash

Paul Blundell
Senior Android Developer at Novoda

With targeting Marshmallow, 6.0, API 23, the latest version of Android*, strange things can happen if you don't get your permission flow correct. The code seems legit and yet it crashes every time. You have all the correct permissions in your AndroidManifest, you call the correct API to get your data. It runs perfectly well on your other emulator (pre-Marshmallow without realising). Let's debug together.

    以 Marshmallow, 6.0, API 23(最新版的安卓)为标的,如果权限流程不正确,有可能发生稀奇古怪的事情。 程序代码看起来完全合法,但还是每次都崩溃。 AndroidManifest 中的权限全都正确,也调用了正确的 API 获取数据。 程序在其他模拟器上运行完美 (Marshmallow 之前未意识到)。 让我们一起来调试。

    权限分为两大类:dangerous(危险)和 normal(正常)。 本文其余部分明确讨论 dangerous(危险)权限。 在此处可阅读其差别的更多信息。

  • У вашего приложения есть разрешение на неудачное завершение работы

    При создании приложения для Marshmallow, 6.0, API 23 — новейшей версии ОС Android — могут происходить странные вещи, если оно не получило нужных разрешений. Код кажется правильным, но каждый раз завершается неудачно. В файле AndroidManifest указаны все необходимые разрешения, вы можете корректно вызывать программный интерфейс API для получения данных. Все идеально работает на другом эмуляторе (с предварительным выпуском Marshmallow). Давайте займемся отладкой.

    Apuntando a Marshmallow, 6.0, API 23, la versión más reciente de Android, pueden suceder cosas extrañas si no recibe bien el flujo de permisos. El código parece legítimo y aun así colapsa todo el tiempo. Tiene todos los permisos correctos en AndroidManifest, convoca a la API correcta para obtener los datos. Se ejecuta perfectamente bien en su otro emulador (pre Marshmallow sin darse cuenta). Depuremos juntos.

    Na versão mais recente do Android (Marshmallow, 6.0, API 23), coisas estranhas podem acontecer se você não configurar corretamente seu fluxo de permissões. O código parece em ordem, mas para de funcionar o tempo todo. Você tem todas as permissões corretas no AndroidManifest, invoca a API correta para obter seus dados. Ele roda perfeitamente em seu outro emulador (anterior ao Marshmallow, sem explicação). Vamos depurar juntos.

  • Project template to develop WPF applications with Intel® RealSense™

    In Visual Studio Gallery is available the first version of my project templates for WPF applications that allows you to create applications written in C# that use Intel® RealSense™ SDK.

    The template can be downloaded directly from within Visual Studio by using the tool "Extensions and Updates" as shown in the next figure:

    Multithreaded Parallel Selection Sort Algorithm Using the Power of OpenMP* Performance Library

    The main purpose of the following article is to demonstrate the using of OpenMP library supported by Intel® C++ Compiler to implement an efficient parallel code based on the example of a multithreaded parallel sorting algorithm implementation. In this article, we’ll unveil the most basic features of OpenMP library that effectively provides the high performance acceleration to the sequential code that implements the trivial selection sort algorithm. Also we’ll closely discuss the parallel programming techniques that can be used to avoid the number of issues such as “data race condition” and “data flow dependency" that might be incurred during the following code parallel performance optimization. We’ll also discuss the aspects of the multithreaded parallel code performance measurement assessment using Intel® VTune™ Amplifier XE analyser by running the following parallel code on the modern symmetric multi-core Intel® CPUs such as Intel® Core™ i7 and Intel® Xeon™ E5 processors family.
