检查Marshmallow的许可

Question

我请求Marshmallow的权限有问题，我有这个功能

private void requestPermission() {
    if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)) {
        Toast.makeText(this, "GPS permission allows us to access location data. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
    } else {
        ActivityCompat.requestPermissions(this, new String[]
                {Manifest.permission.ACCESS_FINE_LOCATION}, MY_LOCATION_REQUEST_CODE);
    }
}

还有我的进口货

import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;

我对build.gradle有依赖性

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.android.support:design:25.1.0'

compile 'com.google.android.gms:play-services:10.0.1'
compile 'com.google.code.gson:gson:2.8.0'
compile 'com.android.support:cardview-v7:25.1.0'
compile 'com.android.support:recyclerview-v7:25.1.0'
compile 'com.jakewharton:butterknife:8.4.0'
compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.android.support:support-v4:25.1.0'

compile 'com.github.JakeWharton:ViewPagerIndicator:2.4.1'
testCompile 'junit:junit:4.12'
androidTestCompile 'com.android.support.test:runner:0.5'
androidTestCompile 'com.android.support.test:rules:0.5'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
androidTestCompile 'com.android.support:support-annotations:25.1.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'

compile 'com.facebook.android:facebook-android-sdk:4.19.0'
compile 'com.parse:parsefacebookutils-v4-android:1.10.4@aar'
compile 'com.parse:parse-android:1.13.1'

我得到

"无法解析"ActivityCompat.shouldShowRequestPermissionRationale"和"ActivityCompat.requestPermissions"中的方法"

关于可能发生的事情的任何想法？

Answer 1

我建立了一个解决方案，改变了进口

compile 'com.github.JakeWharton:ViewPagerIndicator:2.4.1'

自

compile('fr.avianey.com.viewpagerindicator:library:2.4.1') {
    exclude group: 'com.google.android', module: 'support-v4'
}

它解决了一切

这可能会有所帮助。它显示了如何检查是否已授予权限，并请求新的权限（在本例中是录制音频和写入外部存储）

if (ContextCompat.checkSelfPermission(MainActivity.this,
                    Manifest.permission.WRITE_EXTERNAL_STORAGE) + ContextCompat
                    .checkSelfPermission(MainActivity.this,
                            Manifest.permission.RECORD_AUDIO)
                    != PackageManager.PERMISSION_GRANTED) {
                if (ActivityCompat.shouldShowRequestPermissionRationale
                        (MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) ||
                        ActivityCompat.shouldShowRequestPermissionRationale
                                (MainActivity.this, Manifest.permission.RECORD_AUDIO)) {
                    mToggleButton.setChecked(false);
                    Snackbar.make(findViewById(android.R.id.content), R.string.label_permissions,
                            Snackbar.LENGTH_INDEFINITE).setAction("ENABLE",
                            new View.OnClickListener() {
                                @Override
                                public void onClick(View v) {
                                    ActivityCompat.requestPermissions(MainActivity.this,
                                            new String[]{Manifest.permission
                                                    .WRITE_EXTERNAL_STORAGE, Manifest.permission.RECORD_AUDIO},
                                            REQUEST_PERMISSIONS);
                                }
                            }).show();
                } else {
                    ActivityCompat.requestPermissions(MainActivity.this,
                            new String[]{Manifest.permission
                                    .WRITE_EXTERNAL_STORAGE, Manifest.permission.RECORD_AUDIO},
                            REQUEST_PERMISSIONS);
                }
            } else {
                (function here)
            }
