How to call a android/native service from a native/android (java) code

本文档详细介绍了Android应用程序如何实现Java层与Native(C/C++)层的服务互相调用。包括从Native层调用Android服务的方法、如何连接到Binder C++服务、以及Android远程服务的调用示例等内容。
### IntelliJ IDEA IO Error Solution When encountering an IO error with the message 'Got minus one from a read call', this typically indicates that there is an issue related to network connections or file reading operations within the application running under IntelliJ IDEA. The problem can arise due to several reasons, including corrupted files, incorrect configurations, or issues with plugins. To address such errors effectively: #### Verify Project Configuration Ensure project settings are correctly configured especially when dealing with external libraries or native code integration as shown in Gradle configuration examples[^1]: ```groovy android { sourceSets { main { jniLibs.srcDirs = ['native-libs'] jni.srcDirs = [] // disable automatic ndk-build } } } ``` This ensures proper handling of JNI libraries which might otherwise cause unexpected behavior during runtime leading to potential IO exceptions. #### Check Network Settings If the application involves networking components, verify proxy settings inside IntelliJ IDEA preferences since misconfigured proxies could lead to premature closure of streams causing `-1` returns on reads indicating end-of-file was reached unexpectedly. #### Update Plugins and IDE Keeping both the development environment along with any relevant plugins up-to-date helps mitigate compatibility problems between different versions of tools used throughout the software stack. For instance, ensuring Maven projects have their lifecycle phases properly set so tasks like packaging execute without hitches[^2]: ```bash mvn package ``` Running `mvn clean install` may also help clear out old artifacts potentially interfering with current builds. #### Review Codebase for Resource Management Issues Inspect areas where input/output operations occur looking specifically at how resources are opened/closed. Improper management here often results in socket timeout errors manifesting through similar symptoms described by the user.
