1、在AndroidManifest.xml中添加如下代码
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="app的包名.fileprovider"
android:grantUriPermissions="true"
android:exported="false"
>
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
2、在res目录下新建一个xml文件夹,并且新建一个file_paths的xml文件(如下图)
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path path="Android/data/app的包名/" name="files_root" />
<external-path path="." name="external_storage_root" />
</paths>
4、修改代码适配Android N
public static void installApkFile(Context context, String filePath) {
Intent intent = new Intent(Intent.ACTION_VIEW);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Uri contentUri = FileProvider.getUriForFile(context, "com.yuneec.android.saleelfin.fileprovider", new File(filePath));
intent.setDataAndType(contentUri, "application/vnd.android.package-archive");
} else {
intent.setDataAndType(Uri.fromFile(new File(filePath)), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
}
context.startActivity(intent);
}
再贴一个启动相机的
public static void startCamera(Activity activity) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
//适配7.0拍照取uri的处理
if(Build.VERSION.SDK_INT < 24){
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(
Environment.getExternalStorageDirectory(), TMP_PATH)));
}else{
Uri uri= FileProvider.getUriForFile(activity,"com.huikeyun.teacher.fileprovider",new File(
Environment.getExternalStorageDirectory(), TMP_PATH));
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION );//添加这一句表示对目标应用临时授权该Uri所代表的文件
}
activity.startActivityForResult(intent, CAMERA_WITH_DATA);
}
