android 添加，删除程序

1. 安装程序

String fileName = Environment.getExternalStorageDirectory() + "/myApp.apk";
Intent intent = new Intent(Intent.ACTION_VIEW);

intent.setDataAndType(Uri.parse("file://" + filePath),"application/vnd.android.package-archive");
//或者
//intent.setDataAndType(Uri.fromFile(new File(fileName)), "application/vnd.android.package-archive");

startActivity(intent);

2.删除程序

Uri packageURI = Uri.parse("package:com.android.myapp");
Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI);
startActivity(uninstallIntent);

默认是不支持安装非市场程序的 因此判断一下

int result = Settings.Secure.getInt(getContentResolver(), Settings.Secure.INSTALL_NON_MARKET_APPS, 0);
if (result == 0) {
// show some dialog here
// ...
// and may be show application settings dialog manually
Intent intent = new Intent();
intent.setAction(Settings.ACTION_APPLICATION_SETTINGS);
startActivity(intent);
}
