一行代码完成Android 7 FileProvider适配~

适配FileProvide需要声明provider，编写xml，以及在代码中做版本适配等...

可以抽取一个小库简化这些重复性操作，避免重复声明provider，编写xml，以及在代码中做版本适配...

使用

compile 'com.zhy.base:fileprovider:1.0.0'

通过FileProvider7这个类完成uri的获取即可，例如：

• FileProvider7.getUriForFile
• FileProvider7.setIntentDataAndType
• FileProvider7.setIntentData

示例一 拍照

private static final int REQUEST_CODE_TAKE_PHOTO = 0x110;
private String mCurrentPhotoPath;

public void takePhotoNoCompress(View view) {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        String filename = new SimpleDateFormat("yyyyMMdd-HHmmss", Locale.CHINA)
                .format(new Date()) + ".png";
        File file = new File(Environment.getExternalStorageDirectory(), filename);
        mCurrentPhotoPath = file.getAbsolutePath();
	     // 仅需改变这一行
        Uri fileUri = FileProvider7.getUriForFile(this, file);

        takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
        startActivityForResult(takePictureIntent, REQUEST_CODE_TAKE_PHOTO);
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK && requestCode == REQUEST_CODE_TAKE_PHOTO) {
        mIvPhoto.setImageBitmap(BitmapFactory.decodeFile(mCurrentPhotoPath));
    }
    // else tip?

}

示例二 安装apk

public void installApk(View view) {
    File file = new File(Environment.getExternalStorageDirectory(),
            "testandroid7-debug.apk");
    Intent intent = new Intent(Intent.ACTION_VIEW);
    // 仅需改变这一行
    FileProvider7.setIntentDataAndType(this,
            intent, "application/vnd.android.package-archive", file, true);
    startActivity(intent);
}

android8.0分享无法分享图片;

尝试在8.0的系统上分享图片的时候，分享的应用提示无法找到文件;
但是我在相册中分享是成功的;

install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)

app更新时，已经授予了读写权限，但是加上install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)这句后，android7.0就会报Permission Denial，提示没有授权；我去掉install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)，app能够安装，但是安装完成后的页面直接闪退，不能提示用户打开app,请问这是什么原因呢；

@OverRide
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(DownloadManager.ACTION_DOWNLOAD_COMPLETE)) {
Intent install = new Intent(Intent.ACTION_VIEW);
//判断是否是AndroidN以及更高的版本
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Uri contentUri = FileProvider.getUriForFile(context, "cn.cloudworkshop.miaoding.fileprovider", file);
//授予读写权限
install.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
// List resInfoList = context.getPackageManager()
// .queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
// for (ResolveInfo resolveInfo : resInfoList) {
// String packageName = resolveInfo.activityInfo.packageName;
// context.grantUriPermission(packageName, contentUri,
// Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
// }

            install.setDataAndType(contentUri, "application/vnd.android.package-archive");
        } else {
            install.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");

        }
        install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(install);
    }
}

发现在Android7.0以上手机上调用安装应用会出现解析安装包出现问题

发现在Android7.0以上手机上调用安装应用会出现解析安装包出现问题
但是安装包是正确的,手动点击可以安装,但是通过代码调起就无法安装

建议自定义一个Provider, 自定义authority后缀, 避免与其他sdk冲突;

如题;

裁剪遇到的问题

intent.putExtra(MediaStore.EXTRA_OUTPUT, desUri); /////是file:/// 不报错 ,改成content://反而报错

java.lang.SecurityException: Permission Denial: writing android.support.v4.content.FileProvider uri content://com.galaxyschool.app.wawaschool.fileprovider/external/lqwawa/wawatong/icon/zoom_icon.jpg from pid=20723, uid=10071 requires the provider be exported, or grantUriPermission()
请问 是啥原因呢
