There are some Android applications which allow user to clone existed application on the phone.
eg: http://fixoptimize.com/app-cloner
Can you explain how these cloners work?
Thank you.

  1. Change the package name in AndroidManifest.xml and re-sign the app. Notice that the xml is binary instead of text in an apk package. Android identify different apps with package name and with package name changed an app would be considered a "new one".

  2. While the simple approach may or may not work (e.g. the app assumes its package name to be constant, or checks its signature) in many cases various other changes should be applied, including also chage the java package name, disable signature check, change string literals which are assumed path names containing a package name. All these would (likely) require decompiling and deassambling dex and even native codes, which is not only hard but illegal as well.


  3. The modern way: Sandboxify the app. A sandbox environment would be created, within which the app being "cloned" is not actually cloned and remains unchanged. The sandbox would intercept all communication between the cloned app and the system, the user and other apps so it's transparent and stable. Neither the app nor the user would notice that the app's being sandboxed. And this most likely keeps legal concerns away unless a emulator is also outlawed. There are open source sandbox apps on github that you could examine and, well, copy.

    It would sound like advertising so i didn't add links in the answer. But as you want, github.com/asLody/VirtualApp would be one. While it's a sandbox app for users to install many apps inside, it's also possible to contain only one app so it would look like the app itself. github.com/android-hacker/exposed might be an similiar implementation, or not. And consider method (1) of the answer first.

Monofisismo

Image
Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri...

Olmecas

Image
Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México...
