本文实例为大家分享了android实现分享图片到朋友圈功能的具体代码，供大家参考，具体内容如下
在Android7.0中，系统对scheme为file://的uri进行了限制，所以通过这种uri来进行分享的一些接口就不能用了，比如使用代码来调用分享朋友圈的接口。
此时就得使用其他的URI scheme来代替 file://，比如MediaStore的 content://。直接上代码：

还有一种方式，就是FileProvider来分享文件，操作起来稍微复杂一点，大概代码如下（代码功能是拍照的）：

return image;
}
static final int REQUEST_TAKE_PHOTO = 1;
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
...
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}

还要在manifest中声明这个FileProvider

<application>

<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.example.android.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths"></meta-data>
</provider>
...
</application>
|
在res/xml/文件夹下新建文件file_paths.xml：
|

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images" path="Android/data/com.example.package.name/files/Pictures" />
</paths>
