Question

我正在使用Android Studio 2.1.1。从API 22升级到API 23之前有效的基本功能不再起作用。

2个例子：

1）获取返回API 22中指定路径中所有文件和文件夹的文件列表，现在在API 23中文件为空：

    File f = new File(dirPath);
    File[] files = f.listFiles();

2）从设备返回帐户返回API 22中的所有电子邮件帐户，现在在API 23 帐户中为空：

    Pattern emailPattern = Patterns.EMAIL_ADDRESS;
    accounts = AccountManager.get(this).getAccounts();

其他例子不能简单描述，所以我希望只给出两个例子就足够了。

我的API 22的gradle文件：

apply plugin: 'com.android.application'
android {
    compileSdkVersion 22
    buildToolsVersion '22.0.1'
    compileOptions.encoding = 'windows-1251'

    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
    defaultConfig {
        applicationId "com.soft.StudyNJoy"
        minSdkVersion 14
        targetSdkVersion 22
        multiDexEnabled true

        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_7
            targetCompatibility JavaVersion.VERSION_1_7
        }
    }

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles 'proguard-android.txt', 'proguard-project.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.android.support:cardview-v7:22.2.1'
    compile 'com.android.support:design:22.2.1'
    compile 'com.android.support:support-v4:22.2.1'
    compile 'com.google.code.gson:gson:2.2.4'
    compile 'com.google.guava:guava:18.0'
    compile files('libs/achartengine-1.1.0.jar')
    compile files('libs/commons-codec.jar')
    compile files('libs/commons-io-2.4.jar')
    compile files('libs/commons-net-3.3.jar')
    compile files('libs/dropbox-android-sdk-1.6.jar')
    compile files('libs/httpmime-4.0.3.jar')
    compile files('libs/iSpeech-SDK-1.4.2.jar')
    compile files('libs/json_simple-1.1.jar')
    compile files('libs/PayPal_MPL.jar')
    compile files('libs/sqlcipher.jar')
}

升级到API 23后的gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.3'
    compileOptions.encoding = 'windows-1251'

    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
    defaultConfig {
        applicationId "com.soft.StudyNJoy"
        minSdkVersion 14
        targetSdkVersion 23
        multiDexEnabled true

        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_7
            targetCompatibility JavaVersion.VERSION_1_7
        }
    }

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles 'proguard-android.txt', 'proguard-project.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support:cardview-v7:23.4.0'
    compile 'com.android.support:design:23.4.0'
    compile 'com.android.support:support-v4:23.4.0'
    compile 'com.google.code.gson:gson:2.4'
    compile 'com.google.guava:guava:18.0'
    compile files('libs/achartengine-1.1.0.jar')
    compile files('libs/commons-codec.jar')
    compile files('libs/commons-io-2.4.jar')
    compile files('libs/commons-net-3.3.jar')
    compile files('libs/dropbox-android-sdk-1.6.jar')
    compile files('libs/httpmime-4.0.3.jar')
    compile files('libs/iSpeech-SDK-1.4.2.jar')
    compile files('libs/json_simple-1.1.jar')
    compile files('libs/PayPal_MPL.jar')
    compile files('libs/sqlcipher.jar')
}

所有必要的权限都在清单文件中 - 从API 22升级到API 23期间没有任何变化。

有谁知道什么可能是错的？
在此先感谢，亲切的问候格哈德

Answer 1

In API 23 there is two kind of permissions, normal - that will be granted automatically if you add it to manifest, and dangerous - that should be granted by user via UI. ACCOUNT_MANAGER - is second kind of permissions. You need to request the permission method in this case first - https://developer.android.com/training/permissions/requesting.html

Answer 2

You have to get Runtime permission for API 23.
