android stdio 开发时使用系统权限和hide函数报错的解决方法

1:android stdio 开发时使用系统权限报错,为了编译成功可以关闭Using system app permission

这样就不会报错了

2:android stdio3.0 调用hide函数,添加系统jar文件,我们已InputManager.getInstance()方法举例

getInstance在android stdio sdk中为hide,在代码中直接使用会编译失败

    /**
     * Gets an instance of the input manager.
     *
     * @return The input manager instance.
     *
     * @hide
     */
    public static InputManager getInstance() {
        synchronized (InputManager.class) {
            if (sInstance == null) {
                try {
                    sInstance = new InputManager(IInputManager.Stub
                            .asInterface(ServiceManager.getServiceOrThrow(Context.INPUT_SERVICE)));
                } catch (ServiceNotFoundException e) {
                    throw new IllegalStateException(e);
                }
            }
            return sInstance;
        }
    }

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final KeyEvent kEvent = new KeyEvent(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(),
                KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_MENU, 0, 0,
                KeyCharacterMap.VIRTUAL_KEYBOARD, 0,KeyEvent.FLAG_FROM_SYSTEM | KeyEvent.FLAG_VIRTUAL_HARD_KEY,
                InputDevice.SOURCE_KEYBOARD);

        //调用hide函数
        InputManager.getInstance().injectInputEvent(kEvent,
                InputManager.INJECT_INPUT_EVENT_MODE_WAIT_FOR_FINISH);
    }

我们可以使用系统生存的jar文件,编译生存的InputManager.class文件在framework.jar文件中out\target\common\obj\JAVA_LIBRARIES\framework_intermediates\classes.jar,修改文件为framework.jar(可以不改),

导致工程libs目录

右键工程选择 open moudle settings 设置文件为Compile only(只产于编译)

android stdio 开发时使用系统权限和hide函数报错的解决方法

查看 app下的build.gradle会生存如下内容 compileOnly files('libs/framework.jar')

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    compileOnly files('libs/framework.jar')
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:26.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

最后一步编译时选择我们的jar文件优先,在工程的build.gradle(不是app下的)中添加

    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs.add('-Xbootclasspath/p:app\\libs\\framework.jar')
        }
    }

allprojects {
    repositories {
        google()
        jcenter()
    }

    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs.add('-Xbootclasspath/p:app\\libs\\framework.jar')
        }
    }
}

并在app.iml文件中把我们的jar移动到SDK前面,否则代码会提示有错(虽然能编译通过)

    <orderEntry type="library" name="__local_aars__:D.\Users\caron_wy\MyApplication4\app\libs\framework.jar:[email protected]" level="project" />
    <orderEntry type="jdk" jdkName="Android API 26 Platform" jdkType="Android SDK" />
    <orderEntry type="sourceFolder" forTests="false" />
