Android 系统跳转实现分享功能（如 微信 朋友圈 QQ Q
CSDN地址： https://blog.csdn.net/shuai497331206
前者基本都是一个实现思路， 唯独微博实现比较特殊一点。
我对两个类做了封装 只要配置没问题， 拿去直接用。
先来一波配置
清单文件下
android:name="androidx.core.content.FileProvider"
android:authorities="包名.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths_public"/>
下的文件 Context.getExternalCacheDir目录下的目录-->
name="external_cache_path"
path="."/>
<!--配置root-path。这样子可以读取到sd卡和一些应用分身的目录，否则微信分身保存的图片，就会导致 java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/999/tencent/MicroMsg/WeiXin/export1544062754693.jpg，在小米6的手机上微信分身有这个crash，华为没有
-->
name="root-path"
path=""/>
...
（3） network_security_config
<?xml version="1.0" encoding="utf-8"?>
因为是需要内容提供者 跳转三方应用的页面 所以必须要添加， 还有就是 android7.0以后的权限

}
使用时候 （切记 切记 切记 图片必须是下载到本地的！！！）
动态申请权限
private static final int REQUEST_EXTERNAL_STORAGE = 1;
private static String[] PERMISSIONS_STORAGE = {
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE
};
//动态获取内存存储权限
public void verifyStoragePermissions(Activity activity) {
int permission = ActivityCompat.checkSelfPermission(activity,
Manifest.permission.WRITE_EXTERNAL_STORAGE);
if (permission != PackageManager.PERMISSION_GRANTED) {
if (!ActivityCompat.shouldShowRequestPermissionRationale(ShareDemoActivity.this,
Manifest.permission.READ_EXTERNAL_STORAGE)) {
ActivityCompat.requestPermissions(ShareDemoActivity.this,
PERMISSIONS_STORAGE,
REQUEST_EXTERNAL_STORAGE);
}
ActivityCompat.requestPermissions(ShareDemoActivity.this,
PERMISSIONS_STORAGE,
REQUEST_EXTERNAL_STORAGE);
}
while ((ContextCompat.checkSelfPermission(ShareDemoActivity.this,
Manifest.permission.READ_EXTERNAL_STORAGE))!= PackageManager.PERMISSION_GRANTED) {
}
}
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
}
完成！！！！！
