在Oreo 8.0中不工作的其他应用程序上共享图像

Question

我正在使用此代码在Whatsapp、Facebook和Instagram等网站上共享图像。此代码在API 25以下运行良好，但在API 25以上不起作用。

Intent share = new Intent("android.intent.action.SEND");
                share.setType("image/jpeg");
                share.putExtra("android.intent.extra.STREAM", Uri.parse(this.imgUrl));
                startActivity(Intent.createChooser(share, "via"));

Answer 1

试试这个：

Intent shareIntent = new Intent();
     shareIntent.setAction(Intent.ACTION_SEND); 
     shareIntent.putExtra(Intent.EXTRA_STREAM, uriToImage); 
     shareIntent.setType("image/jpeg");
startActivity(Intent.createChooser(shareIntent,getResources().getText(R.string.send_to)));

Answer 2

首先确保您已添加权限

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

然后使用此代码

Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
Uri imageUri =  Uri.parse(this.imgUrl);                                
share.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(Intent.createChooser(share, "Select"));

Answer 3

如果Target etSdkVersion高于24，则使用Provider授予访问权限。

创建xml文件：res\xml\provider\u路径。xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>

现在在AndroidManifest中添加一个提供者。xml文件

<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
    android:name="android.support.FILE_PROVIDER_PATHS"
    android:resource="@xml/provider_paths"/>
</provider>

并用你的代码替换它

Intent share = new Intent("android.intent.action.SEND");
            share.setType("image/jpeg");
Uri uri = FileProvider.getUriForFile(MainActivity.this, BuildConfig.APPLICATION_ID+ ".provider",new File(this.imgUrl));
            share.putExtra("android.intent.extra.STREAM", uri);

            startActivity(Intent.createChooser(share, "via"));

使现代化

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<files-path name="external_files" path="."/>
<cache-path name="external_files" path="."/>
<external-path name="external_files" path="."/>
<external-files-path name="external_files" path="."/>
<external-cache-path name="external_files" path="."/>
</paths>
