Question

安卓工作室 3.6

安卓 6.0

应用程序/build.gradle:

android {
    //viewBinding.enabled = true
    dataBinding {
        enabled = true
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    compileSdkVersion 29
    buildToolsVersion "29.0.2"
    defaultConfig {
        minSdkVersion 23
        targetSdkVersion 29
        versionCode 2
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation('com.crashlytics.sdk.android:crashlytics:2.10.1@aar') { transitive = true; }
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0-rc01'
    implementation 'com.google.android.material:material:1.2.0-alpha01'

    implementation 'androidx.localbroadcastmanager:localbroadcastmanager:1.0.0'
    implementation 'androidx.lifecycle:lifecycle-extensions:2.1.0'
    implementation 'androidx.viewpager2:viewpager2:1.0.0-beta05'
    implementation 'com.journeyapps:zxing-android-embedded:4.0.0'
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.0'
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.0"

    testImplementation 'junit:junit:4.12'

    implementation "androidx.core:core-ktx:+"
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

}

在我的 Activity 中

class QRScanActivity : RootActivity() {
    private lateinit var dataBinding: QrScanActivityBinding
    private val REQUEST_PERMISSION = "REQUEST_PERMISSION"
    private val REQUEST_CODE_CAMERA = 1
private lateinit var beepManager: BeepManager

 override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        dataBinding =
            DataBindingUtil.setContentView<QrScanActivityBinding>(this, R.layout.qr_scan_activity)
        dataBinding.setHandler(this)
        init()
    }

 private fun initLogic() {
        dataBinding.decoratedBarcodeView.decodeContinuous(object : BarcodeCallback {
            override fun barcodeResult(result: BarcodeResult?) {
                beepManager.playBeepSoundAndVibrate();
                finish();
            }

            override fun possibleResultPoints(resultPoints: MutableList<ResultPoint>?) {

            }
        })
}

在 xml 布局中:

<com.journeyapps.barcodescanner.DecoratedBarcodeView
            android:id="@+id/decoratedBarcodeView"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_marginBottom="@dimen/default_margin"
            app:layout_constraintBottom_toTopOf="@+id/qrButtonScan"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/toolBarContainer" />

成功工作 安卓 9.0 .好的。

但是当我开始时 安卓 6.0 我得到错误:

Tough call there. On the one hand I can't publish the Android appanymore, so it's kind of 'deprecated'. The core library can still beused outside Android, or in another Android app. That app would haveto target API 24, yes. The app in the project can't target API 24, soit also doesn't quite make sense to leave it in a state where it won'trun on API < 24. Another solution is to modify the Android app todepend on the 3.3.x core library and leave it there.

Please read all of the messages above. You can a) use 3.3.x, or b)target API 24.
