android - requestPermissions 未在设备上显示权限对话框，在 Android studio 模拟器上运行良好

Question

面对 requestPermissions Activity 方法的奇怪问题。现在显示我是否在设备上调试。如果我在 Android Studio 模拟器上调试应用程序，效果很好。 以下是请求权限的代码。

public boolean isStoragePermissionGranted() {
        if (Build.VERSION.SDK_INT >= 23) {
            if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED ) {
                return true;
            } else {
                    requestPermissions(new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
                return false;
            }
        } else { //permission is automatically granted on sdk<23 upon installation
            return true;
        }
    }

这是AndroidManifest

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

和build.gradle

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "abc.xyz"
        minSdkVersion 23
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

我运行调试的设备是 OnePlus 1。我错过了什么吗？

以下是尝试请求权限时的一些额外日志:

Answer 1

改变

requestPermissions(new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);

到

ActivityCompat.requestPermissions(this,new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
