Question

朋友们，我实现的应用程序是我的应用程序扫描qr代码，我使用com.google.zxing：core：3.2.1库，下面是我的gradle文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.pkg"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:22.+'
    compile 'com.android.support:design:22.+'
    compile 'de.hdodenhof:circleimageview:2.0.0'
    compile 'com.journeyapps:zxing-android-embedded:3.2.0@aar'//Add dependency
    compile 'com.google.zxing:core:3.2.1'
}

我打电话扫描下面的条形码

mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
        IntentIntegrator integrator = new IntentIntegrator(ActivitySubTask.this);
          scanid=mArrayListGetSubLocations.get(i).getSubid();
        Log.d("scanid ",String.valueOf(scanid));
        integrator.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
        integrator.setPrompt("Scan");
        integrator.setCameraId(0);
        integrator.setBeepEnabled(false);
        integrator.setBarcodeImageEnabled(false);
        integrator.initiateScan();
    }
});

上面的代码在4.0到5.1版本的设备上工作正常，但是当我在6.0版本的设备中测试它是崩溃应用程序，下面是我的错误消息来自我的Logcat

修改

<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

我通过从22

制作版本23来改变gradle文件来制作解决方案

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.pkg"
    minSdkVersion 15
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
         }
     }
  }

 dependencies {
 compile fileTree(dir: 'libs', include: ['*.jar'])
 testCompile 'junit:junit:4.12'
 compile 'com.android.support:appcompat-v7:23.+'
 compile 'com.android.support:design:23.+'
 compile 'de.hdodenhof:circleimageview:2.0.0'
 compile 'com.journeyapps:zxing-android-embedded:3.2.0@aar'//Add     dependency
  compile 'com.google.zxing:core:3.2.1'
 }
